All MasterPact circuit breakers are equipped with the MicroLogic trip system to protect power circuits and loads. MicroLogic trip systems use a set of current transformers (called CTs or sensors) to sense current, a trip unit to evaluate the current, and a tripping solenoid to trip the circuit breaker. Adjustable rotary switches on the trip unit allow the user to set the proper overcurrent or equipment ground-fault current protection required in the electrical system. If current exceeds a set value for longer than its set time delay, the trip system opens the circuit breaker. Alarms may be programmed for remote indications. Measurements of current, voltage, frequency, power, and power quality optimize continuity of service and energy management. MicroLogic trip units can be changed on-site.

Integration of protection functions in the Application Specific Integrated Circuit (ASIC) electronic component used in all MicroLogic trip units guarantees a high degree of reliability and immunity to conducted or radiated disturbances. On MicroLogic P and H trip units, advanced functions are managed by an independent microprocessor.

MasterPact circuit breakers are shipped with the long-time pickup switch set at 1.0 and all other trip unit adjustments set at their lowest settings. Actual settings required for a specific application must be determined by a qualified consultant or plant engineer. A coordination study is recommended to provide coordination between all circuit breakers in the distribution system.

Thermal Imaging

The thermal imaging function protects the cables or bus bars from overheating in case of low amplitude repetitive faults. Such overheating can be due to repetitive motor starting, fluctuating load, intermittent ground faults, or subsequent closing after a fault.

Traditional electronic protection does not protect against repetitive faults because the duration of each overload above the pickup setting is too short to achieve effective tripping. Nevertheless, each overload involves a temperature rise in the installation, the cumulative effect of which could lead to overheating of the system.

The thermal imaging function remembers and integrates the thermal heating caused by each pickup setting overrun. Before tripping, the integrated heating value will reduce the associated time delay and, therefore, the reaction of the trip unit will be closer to the real heating of the power network system.

After tripping, the function will also reduce the time delay when closing the circuit breaker on an overload.

Power Supply Information

Ammeter (A) Trip Unit Without 24 Vdc Power Supply at F1 and F2

  • Provides fault protection for LSIG functions.

  • Provides LED trip indication (powered by an onboard battery).

  • All display functions and trip unit features power-up with current flow on one phase greater than or equal to the values in the table to the left.

  • Ground-fault push-to-trip button works for testing ground fault with current flow on one phase greater than or equal to the values shown in the following table.

Sensor Plug Value (In) Minimum Ground-Fault Pickup
100–250 A 30% of sensor rating
400–1200 A 20% of sensor rating
1600–6300 A 500 A

Ammeter (A) Trip Unit With 24 Vdc Power Supply at F1 and F2

The Ammeter (A) trip unit provides all of the above plus additional functionality when powered by external 24 Vdc power supply:

  • Ammeter and bar graph displays are functional with or without current flowing through the circuit breaker.

  • Trip settings and (Max) current readings can be accessed on the display by pressing navigation button with or without current flowing through the circuit breaker.

  • The ground-fault push-to-trip button works for testing ground fault with or without current flowing through the circuit breaker.

  • Optional Modbus™ communications—also requires a separate 24 Vdc power supply for the circuit breaker communications module.

NOTE: Ground-fault push-to-trip button will also be functional if a hand-held test kit or full-function test kit is powering the trip unit.

Power (P) and Harmonic (H) Trip Unit Without 24 Vdc Power Supply at F1 and F2

The P and H trip units were designed to be used with the external 24 Vdc power supply. The large LCD display requires too much current to be powered by current flow through the circuit breaker. The P and H trip units do have a voltage power supply which will power the trip unit with 100 Vac or more between two phases or phase to neutral. The standard configuration for the voltage probes inside the circuit breaker is at the bottom connections. If the circuit breaker was open in a top fed application, there would be no voltage at the bottom of the circuit breaker and the trip unit would not be powered.

  • Provides fault protection for LSIG functions.

  • Provides LED trip indication (powered by an onboard battery).

NOTE: Ground-fault push-to-trip button works for testing ground fault if the trip unit is powered by the voltage power supply. The ground-fault push-to-trip is also functional if a hand-held test kit or full-function test kit is powering the trip unit.

Power (P) and Harmonic (H) Trip Unit With 24 Vdc Power Supply at F1 and F2

  • Provides all of the above.

  • LCD display and backlight are functional.

  • Ground-fault push-to-trip button works for testing ground fault.

  • All metering, monitoring, and history logs are functional.

  • Communications from trip unit to M2C and M6C programmable contact modules are powered by a 24 Vdc supply at F1 and F2. M6C also requires a 24 Vdc external power supply.

  • Modbus communications—also requires a separate 24 Vdc power supply for the circuit breaker communications module.

NOTE: Ground-fault push-to-trip button will also be functional if hand-held test kit or full-function test kit is powering the trip unit.

MicroLogic Trip UnitsOverview

True RMS Current Sensing

The sensing system responds to the flow of current through the circuit breaker. Electronic trip circuit breakers are limited to ac systems because the electronic trip system uses current transformers to sense the current. The MicroLogic trip unit samples the current waveform to provide true RMS protection through the 15th harmonic.

This true RMS sensing gives accurate values for the magnitude of a non-sinusoidal waveform. Therefore, the heating effects of harmonically distorted waveforms are accurately evaluated.

The MicroLogic H trip unit provides additional sampling of the waveforms to measure and provide waveform capture of harmonic distortion to the 31st harmonic.

MasterPact universal power circuit breakers use MicroLogic electronic trip systems to sense overcurrents and trip the circuit breaker. The MicroLogic basic trip unit is standard and all MasterPact circuit breakers can be equipped with the optional MicroLogic trip systems listed below:

Ammeter Measurements

MicroLogic A trip units measure the true RMS value of currents. They provide continuous current measurement from 0.2 to 20 x In with an accuracy of 1.5% (including sensors). No auxiliary source is needed where I > 0.2 x In. The optional external power supply (24 Vdc) makes it possible to display currents where I < 0.2 x In and to store values of the interrupted current. A digital LCD screen continuously displays the most heavily loaded phase (Imax) or displays the Ia, Ib, Ic, Ig, and (on four-pole circuit breakers only) In stored current and setting values by successively pressing the navigation button.

Communication Network

Four wire Modbus, RTU, RS485 or two wire Modbus, TRU, RS485 plus ULP. See Additional Wiring Information for MasterPact NW NT Circuit Breakers.

In conjunction with an optional communication network, the trip unit transmits the following parameters:

  • Setting values.

  • All ammeter measurements.

  • Tripping causes.

NOTE: Current-based protection functions require no auxiliary power source. When an external power supply is added, the value of the interrupted current is stored by the trip unit. The reset button resets alarms and stored interrupted current indications.

MicroLogic 5.0P and 6.0P Trip Units with Power Metering

Protection Settings

The adjustable protection functions of the 5.0P and 6.0P trip units are
identical to those of MicroLogic A trip unit (overloads, short circuits, equipment ground-fault protection); see MicroLogic 2.0A, 3.0A, 5.0A and 6.0A Trip Units with Ammeter.

These units also feature:

  • Fine adjustment: Within the range below the rotary switch setting, fine adjustments of pickups/delays in steps of 1 A/s (except for short-time and ground-fault) are possible on the keypad or remotely by the communication network.

  • Inverse definite minimum time lag (IDMTL) setting: Coordination with fuse-type or medium-voltage protection systems is optimized by adjusting the long-time delay curve around 6 x Ir axis. This setting ensures better coordination with certain loads.

  • Neutral protection: On three-pole circuit breakers, neutral protection may be set using the keypad or remotely using the communication network to one of four positions:

    — OFF

    — 1/2N (1/2 x In)

    — 1N (1 x In)

    — 2N (2 x In)

NOTE: The neutral protection is disabled if the long-time curve is set to one of the IDMTL protection settings.

Configuring Alarms and Other Protection Functions

When the cover is closed, the keypad may no longer be used to change the protection settings, but it still provides access to the displays for measurements, histories, indicators, etc. Depending on the thresholds and time delays set, the MicroLogic P trip unit monitors current, voltage, power, frequency, and phase sequence. Each threshold overrun may be signalled remotely via the communication network.

Each threshold overrun may be combined with tripping (protection) or an indication carried out by an optional M2C/M6C programmable contact (alarm), or both (protection and alarm).

Maintenance Record

The maintenance record can be consulted using the full-function test kit or remotely via the communication network. It can be used as an aid in troubleshooting and to assist scheduling for device maintenance operations.

Recorded indications include:

  • Highest current measured

  • Operation counter (both cumulative total and total since last reset)

  • Number of test kit connections

  • Number of trips in operating mode

  • Contact wear (MasterPact NW only)

Load Shedding and Reconnection Parameters

Load shedding and reconnection parameters can be set according to the power or the current flowing through the circuit breaker. Load shedding is carried out by a remote computer via the communication network or by an M2C or M6C programmable contact.

Indication Option via Programmable Contacts

The M2C (two contacts) and M6C (six contacts) programmable contacts may be used to signal threshold overruns or status changes. They can be programmed using the keypad on the MicroLogic P and H trip units or remotely using the communication network. These contacts are required to obtain data from the protective relay functions on Type P and Type H trip units.

Communication Network

Four wire Modbus, RTU, RS485—The communication network may be used to:

  • Remotely read parameters for the protection functions.

  • Transmit all the measurements and calculated values.

  • Signal the causes of tripping and alarms.

  • Consult the history files and the maintenance indicator record.

In addition, an event log of the last 100 events and a maintenance record, which is stored in the trip unit memory but not available locally, may be accessed via the communication network.

The Modbus communication system is compatible with Powerlogic™ System Manager™ (SMS) software.

Event Log

The event log may be accessed by a remote computer via the communication network. All events are time stamped and include:

  • Trips

  • Beginning and end of alarms

  • Modifications to settings and parameters

  • Loss of time

  • Overrun of wear indicators

  • Test kit connections

  • Counter resets

  • System faults (thermal self-protection, major fault and minor fault alarms)

MicroLogic 5.0H and 6.0H Trip Units with Harmonic Metering

MicroLogic 6.0H
Trip Unit

In addition to the P functions, the MicroLogic H trip units offer:

  • In-depth analysis of power quality including calculation of harmonics and the fundamentals.

  • Diagnostics aid and event analysis through waveform capture.

  • Customized alarm programming to analyze and track down a disturbance on the ac power system.

  • Systematic time stamping of all events and creation of logs.

Metering

The MicroLogic H trip unit offers all the measurements carried out by the MicroLogic P trip unit, with the addition of phase-by-phase measurements of power and energy as well as calculation of:

  • Current and voltage total harmonic distortion (THD, thd).

  • Current, voltage and power fundamentals (50/60 Hz).

  • Harmonic components (amplitude and phase) up to the 31st current and voltage harmonic.

Waveform Capture

MicroLogic H trip units can capture and store current and voltage waveforms using digital sampling techniques similar to those used in oscilloscopes. Using the information available in the captured waveform, it is possible to determine the level of harmonics as well as the direction and amplitude of the flow of harmonic power.

Users of MicroLogic H trip units can record manually via the keypad the following waveforms:

  • The four currents: Ia, Ib, Ic, and IN

  • The three phase-to-phase voltages: Vab, Vbc, and Vca

Waveforms may be displayed on the graphic screen of MicroLogic H trip units or communicated over a networked system. The recording takes place over one cycle with a measurement range of 0 to 1.5 IN for current and 0 to 690 volts for voltage. The resolution is sixty-four points per cycle.

Customized Alarm Programming

The instantaneous value of each measurement can be compared to user-set high and low thresholds. Overrun of a threshold generates an alarm. Programmable action can be linked to each alarm, including circuit breaker opening, activation of an M2C or M6C contact, recording of measurements in a log, etc.

Event Logs

Each event is recorded with:

  • The date, time, and name of the event.

  • The event characteristics.

Additional Technical Characteristics for Type P and Type H Trip Units

  • Setting the display language: System messages can be displayed in six different languages:

    • English - US

    • English - UK

    • French

    • German

    • Spanish

    • Italian

The desired language is selected via the keypad.

  • Protection functions: All current-based protection functions require no auxiliary source. Voltage-based protection functions are connected to ac power via a voltage measurement input built into the circuit breaker on the bottom side. (Optional external voltage measurement is available.)

  • Accuracy of measurements (including sensors):

    • Voltage (V) 1%

    • Current (A) 1.5% (higher accuracy [1%] may be achieved with special calibration on the current transformer [CT characterization option])

    • Frequency (Hz) 0.1 Hz

    • Power (W) and energy (Wh) 2.5%

    • The MicroLogic H trip unit uses a dedicated metering data chain separate from the protection data chain so that a greater number of data samples can be used for metering. This increases the number of samples taken per time period, which in turn gives the H trip unit a higher degree of metering accuracy.

  • Stored information: The fine setting adjustments, the last 100 events and the maintenance record remain in the trip unit memory even when power is lost.

  • Reset: An individual reset, via the keypad or remotely, will reset alarms, minimum and maximum data, peak values, counters and the indicators.

MicroLogic Trip Unit Functions

Long-Time Trip Functions

Long-Time Trip Functions

The long-time pickup switch sets the maximum current level the circuit breaker will carry continuously. The maximum current level (Ir) is the long-time pickup setting multiplied by the sensor plug amperage (In). If the current exceeds this value for longer than the long-time delay time, the circuit breaker will trip.

The long-time delay switch sets the length of time that the circuit breaker will carry a sustained overload before tripping. Delay bands are labeled in seconds of overcurrent at six times the ampere rating. For maximum coordination, there are eight delay bands. Long-time delay is an “inverse time” characteristic in that the delay time decreases as the current increases.

The trip unit includes an alarm indicator that will be lit continuously when the current is above 100% of the pickup setting.

Short-Time Trip Functions

Short-Time and Instantaneous Trip Functions

The short-time pickup switch sets the short-circuit current level at which the circuit breaker will trip after the set short-time delay. The short-time current (Isd) equals the short-time pickup setting multiplied by the long-time pickup (Ir).

The short-time delay switch sets the length of time the circuit breaker will carry a short circuit within the short-time pickup range. The delay (based on 10 times the ampere rating Ir) can be adjusted to four positions of I2t ramp operation (I2t ON) or five positions of fixed time delays (I2t OFF). I2t ON delay is an “inverse time” characteristic in that the delay time decreases as the current increases. Short-time delay for the 2.0 trip unit is fixed at a delay band of 20 to 80 ms.

Instantaneous Trip Function

The instantaneous pickup switch sets the short-circuit current level at which the circuit breaker will trip with no intentional time delay. The instantaneous current (Ii) is equal to the instantaneous pickup setting multiplied by the sensor plug amperage (In).

The instantaneous function will override the short-time function if the instantaneous pickup is adjusted at the same or lower setting than the short-time pickup. In trip units with both adjustable short-time and instantaneous trip functions, the adjustable instantaneous trip can be disabled by setting Instantaneous pickup to OFF.

Ground-Fault Trip Functions

Ground-Fault Trip Functions

The ground-fault pickup switch sets the current level at which the circuit breaker will trip after the set ground-fault delay. Ground-fault pickup values (Ig) are based on circuit breaker sensor plug (In) only, not on the rating plug multiplier (Ir). Changing the rating plug multiplier has no effect on ground-fault pickup values.

The ground-fault delay switch sets the length of time the circuit breaker will carry ground-fault current which exceeds the ground-fault pickup level before tripping. The delay (based on the sensor plug amperage (In) can be adjusted to four positions of I2t ramp operation (I2t ON) or five positions of fixed time delays (I2t OFF). I2t ON delay is an “inverse time” characteristic in that the delay time decreases as the current increases.

Enerlin'X Communication Wiring System

Modbus Principle

The Modbus RS 485 (RTU protocol) system is an open bus on which communicating Modbus devices (MasterPact NW with Modbus COM, Power Meter PM700, PM800, PowerPact P/Rframe, etc.) are installed. All types of PLCs and microcomputers may be connected to the bus.

Addresses

The Modbus communication parameters (address, baud rate, parity) are entered using the keypad on the MicroLogic A, P, or H trip unit. For a switch, it is necessary to use the Electrical Asset Manager or RSU (Remote Setting Utility) MicroLogic utility.

Number of Devices

The maximum number of devices that may be connected to the Modbus bus depends on the type of device (ComPact circuit breaker with Modbus COM, PM700, PM800, MasterPact circuit breaker, etc.), the baud rate (19200 is recommended), the volume of data exchanged and the desired response time. The RS 485 physical layer offers up to thirty-two connection points on the bus (one master, thirty-one slaves).

Length of Bus

The maximum recommended length for the Modbus bus is 3940 feet (1200 meters).

Bus Power Source

A 24 Vdc power supply is required (less than 20% ripple, insulation class II).

Ethernet Principle

Ethernet is a data link and physical layer protocol defined by IEEE 802 10 and 100 Mbps specifications that connects computer or other Ethernet devices. Ethernet is an asynchronous Carrier Sense Multiple Access with Collision detection (referred as CSMA/CD) protocol. Carrier Sense means that the hosts can detect whether the medium (coaxial cable) is idle or busy.

Multiple Access means that multiple hosts can be connected to the common medium. Collision Detection means a host detects whether its transmission has collided with the transmission of another host (or hosts).

IFE Ethernet interface can be connected to a PC or a laptop over Ethernet. The maximum length of Ethernet cable is 325 feet (100 meters). IFE Ethernet interface + gateway provides a Modbus TCP/IP gateway over Ethernet to enable Modbus TCP communication from a Modbus TCP master to any Modbus slave devices connected to it. The maximum active Modbus TCP client connection is twelve.

IFE Ethernet interface has an embedded web server (web page).

COM Option in Masterpact Circuit Breakers

All Masterpact devices can be fitted with the communication function thanks to the COM option. Masterpact uses the Ethernet or Modbus communications protocol for full compatibility with the supervision management systems.

For fixed and drawout devices, the common communication option is made up of:

BCM ULP Module

  • A BCM ULP module, installed behind the MicroLogic trip unit and supplied with a set of switches (OF, SDE, PF and CH switches), a kit for connection to shunt close (XF) and shunt trip (MX1) communicating voltage releases, and a COM terminal block (inputs E1 to E6). This module is independent of the trip unit and receives and transmits information on the communication network. An infra-red link transmits data between the trip unit and the communication module. (Consumption: 30 mA, 24 V)

and

  • The IFM module, the Modbus interface for connection to the network, contains the Modbus address (1 to 99) declared by the user using the two dials in front. It automatically adapts (baud rate, parity) to the Modbus network in which it is installed.

or

  • The IFE module, the Ethernet interface for low-voltage circuit breakers, enables an intelligent modular unit (IMU) such as a Masterpact NT/NW or PowerPact circuit breaker to be connected to an Ethernet network. Each circuit breaker has its own IFE and a corresponding IP address.

For drawout devices the Cradle Management option must be added:

IO Application Module

The IO (Input/Output) application module for low-voltage circuit breakers is delivered with the drawout devices ordered with the COM option for cradle management. It must be installed on a steel DIN rail that is properly grounded near the device. The IO module must be connected to the ULP system and to the cradle position contacts (CD, CT, CE) that transmit the position of the circuit breaker in the cradle.

For communicating remote control, shunt close (XF) and shunt trip (MX1) communicating voltage releases must be added:

The shunt close (XF) and shunt trip (MX1) communicating voltage releases are equipped for connection to the communication module.

The remote-tripping function shunt trip (MX2) and undervoltage release (MN) are independent of the communication option. They are not equipped for connection to the communication module.

IFE Ethernet Interface

IFE Interface, IFE Interface + Gateway Description

Introduction

IFE Interface

The IFE interface and IFE interface + gateway enable low-voltage circuit breakers such as MasterPact NT/NW or PowerPact P/R-frame to be connected to an Ethernet network.

IFE Interface

Provides Ethernet access to a single low-voltage circuit breaker.

Function: Interface - one circuit breaker is connected to the IFE interface using its ULP port.

IFE Interface + Gateway

Provides Ethernet access to one or several low-voltage circuit breakers.

Functions:

  • Interface - one circuit breaker is connected to the IFE interface using its ULP port.

  • Gateway: several circuit breakers on a Modbus network are connected using the IFE interface + gateway master Modbus port.

IFE Interface + Gateway

IFE Interface, IFE Interface + Gateway Features

  • Dual 10/100 Mbps Ethernet port for simple daisy chain connection.

  • Device profile web service for discovery of the IFE interface, IFE interface + gateway on the LAN.

  • Ethernet interface for MasterPact and PowerPact circuit breakers.

  • Gateway for Modbus-SL connected devices (IFE interface + gateway only).

  • Embedded set-up web pages.

  • Embedded monitoring web pages.

  • Embedded control web pages.

  • Built-in e-mail alarm notification.

IFE Interface, IFE Interface + Gateway Screen

Mounting

The IFE interface and IFE interface + gateway are DIN rail mounted devices. A stacking accessory enables the user to connect several IFMs (ULP to Modbus interfaces) to an IFE interface + gateway without additional wiring.

24 Vdc Power Supply

The IFE interface and the IFE interface + gateway must always be supplied with 24 Vdc.

The IFMs stacked to an IFE interface + gateway have power supplied by the IFE interface + gateway, thus it is not necessary to supply them separately. It is recommended to use a UL listed and recognized limited voltage/limited current or a class 2 power supply with a 24 Vdc, 3 A maximum.

Required Circuit Breaker Communication Modules

The connection to an IFE interface or IFE interface + gateway requires a communication module embedded into the circuit breaker:

  • MasterPact NT/NW (fixed or drawout) circuit breakers: BCM ULP communication module

  • Drawout MasterPact NT/NW circuit breakers: BCM ULP and its respective IO (Input/Output) application module.

All connection configurations for MasterPact NT/NW circuit breakers require the circuit breaker ULP cord. The insulated NSX cord is mandatory for system voltages greater than 480 Vac. When the second ULP RJ45 connector is not used, it must be closed with a ULP terminator (TRV00880).

IFM Modbus Communication Interface

Function

IFM Modbus Communication Interface. Ref.: TRV00210

An IFM Modbus communication interface is required for connection of a MasterPact or PowerPact circuit breaker to a Modbus network as long as this circuit breaker is provided with a ULP (Universal Logic Plug) port. The port is available on the BCM ULP.

Once connected, the circuit breaker is considered as a slave by the Modbus master. Its electrical values, alarm status, open/close signals can be monitored or controlled by a Programmable Logic Controller or any other system.

Characteristics

ULP Port

Two RJ45 sockets, internal parallel wiring.

  • Connection of a single circuit breaker.

  • A ULP line terminator or an FDM121 display unit must be connected to the second RJ45 ULP socket.

  • The RJ45 sockets deliver a 24 Vdc supply fed from the Modbus socket.

  • Built-in test function, for checking the correct connection to the circuit breaker and FDM121 display unit.

Modbus Slave Port

  • Top socket for screw-clamp connector, providing terminals for:

    — 24 Vdc input supply (0 V, +24 V)

    — Modbus line (D1, D2, Gnd) 2-wire Modbus system

  • Lateral socket, for DIN-rail stackable connector. Both top and lateral sockets are internally parallel wired.

  • Multiple IFMs can be stacked, thus sharing a common power supply and Modbus line without individual wiring.

  • On the front face:

    — Modbus address setting (1 to 99): two coded rotary switches

    — Modbus locking pad: enables or disable the circuit breaker remote control and modification of IFM parameters

  • Self-adjusting communication format (Baud rate, parity).
