Trip Units

Available Trip Units

PowerPacT H-, J-, and L-frame circuit breakers offer a range of thermal-magnetic and MicroLogic electronic trip units in interchangeable cases. Thermal-magnetic trip units are designed to open automatically under overload or short circuit. H-frame and J-frame thermal-magnetic circuit breakers contain individual thermal (overload) and instantaneous (short circuit) sensing elements in each pole.

MicroLogic electronic trip units provide intelligent operation, with wide setting ranges make installation upgrades easier. Designed with processing capabilities, MicroLogic trip units can provide measurement information and device operating assistance to supply all of the information required to manage the electrical installation and optimize energy use.

MicroLogic trip units offer excellent measurement accuracy, using a new generation of current transformers combining “iron-core” sensors for self-powered electronics and “air-core” sensors (Rogowski coils) for measurements. The protection functions are managed by an ASIC component that is independent of the measurement functions. This independence ensures immunity to conducted and radiated disturbances and a high level of reliability.

An LED on the front of the electronic trip unit indicates the result of the self-test running continuously on the measurement system and the tripping release. When the green LED is flashing, the links between the CTs, the processing electronics and the Mitop release are operational. The circuit breaker is ready to protect. A minimum current of 15 to 50 A, depending on the device, is required for this function.

The dual adjustment for protection functions on MicroLogic 5/6 consists of:
— an adjustment using rotary switches to set the maximum value
— an adjustment using the keypad or remote controls to fine-tune the setting. This setting may not exceed the first one. It can be read directly on the MicroLogic screen, to within one ampere and a fraction of a second.

NOTE: All the trip units have a transparent sealable cover that protects access to the adjustment rotary switches.

For MicroLogic trip unit features, see PowerPacT H-, J-, and L-frame Circuit Breaker Trip Units.

MicroLogic 3 Trip Units

MicroLogic 3 trip units can be used on PowerPacT H-, J-, and L-Frame circuit breakers with performance levels D/G/J/L.

They provide:

standard protection of distribution cables
indication of:
- overloads (using LEDs)
- overload tripping (using the SDx relay module)

Circuit breakers equipped with MicroLogic 3 trip units can be used to protect distribution systems supplied by transformers.

Protection

Settings are made using the adjustment rotary switches.

Overloads: Long time protection (I_r)

Inverse time protection against overloads with an adjustable current pick-up I_r set using a rotary switch and an adjustable time delay t_r.

Neutral protection

On three-pole L-frame circuit breakers, neutral protection is not possible.
On four-pole L-frame circuit breakers, neutral protection may be set using a three-position switch:
- switch position 4P 3D: neutral unprotected
- switch position 4P 3D + N/2: neutral protection at half the value of the phase pick-up, (0.5 x I_r)
- switch position 4P 4D: neutral fully protected at I_r

Front indicators

The green “Ready” LED blinks slowly when the electronic trip unit is ready to provide protection. It indicates the trip unit is operating correctly.
Overload pre-alarm LED: steady on when I > 90% I_r
Overload LED: steady on when I > 105% I_r

Remote indicators

An overload trip signal can be remotely checked by installing an SDx relay module inside the circuit breaker. This module receives the signal from the MicroLogic electronic trip unit through an optical link and makes it available on the terminal block. The signal is cleared when the circuit breaker is reclosed. See SDx Module.

Trip Unit Power Requirements

Frame		Power-Up Requirement
H-Frame, 60 A	60 A	>15 A
	100 A	>15 A
	150 A	>30 A
J-Frame, 250 A	250 A	>30 A
L-Frame, 600 A	400 A	>50 A
L-Frame, 600 A	600 A	>50 A

Protection

Settings can be adjusted in two ways, using the rotary switches and/or the keypad.

The keypad can be used to make fine adjustments in 1 A steps below the maximum value defined by the setting on the rotary switch.
Access to setting modifications using the keypad is protected by a locking function displayed on the screen and controlled by a microswitch.
The lock is activated automatically if the keypad is not used for 5 minutes.
Access to the microswitch is protected by a transparent, sealable cover.
With the cover closed, it is still possible to display the various settings and measurements using the keypad.

Overloads: Long-Time Protection (I_r)

Inverse time protection against overloads with an adjustable current pick-up I_r is set using a rotary switch or the keypad for fine adjustments. The time delay t_r is set using the keypad.

Short-Circuits: Short-Time Protection (I_sd)

Short-circuit protection with an adjustable pick-up I_sd and adjustable time delay t_sd, with the possibility of including a portion of an inverse time curve (I²t On).

Short-Circuits: Instantaneous Protection (I_i)

Instantaneous protection with adjustable pick-up I_i.

Additional Ground Fault Protection (I_g) on MicroLogic 6 Trip Units

Residual type ground-fault protection with an adjustable pick-up I_g and adjustable time delay t_g. Possibility of including a portion of an inverse time curve (I²t On).

Neutral Protection

On four-pole circuit breakers, this protection can be set using the keypad:
- Off: neutral unprotected
- 0.5: neutral protection at half the value of the phase pick-up (0.5 x I_r)
- 1.0: neutral fully protected at I_r
- OSN: Oversized neutral protection at 1.6 times the value of the phase pick-up.
  Used when there is a high level of 3rd order harmonics (or orders that are multiples of 3) that accumulate in the neutral and create a high current. In this case, the device must be limited to I_r = 0.63 x I_n for the maximum neutral protection setting of 1.6 x I_r.
With three-pole circuit breakers, the neutral can be protected by installing an external neutral sensor with the output (T1, T2) connected to the trip unit.

Zone Selective Interlocking (ZSI)

A ZSI terminal block may be used to interconnect a number of MicroLogic trip units to provide zone selective interlocking for short-time (I_sd) and ground-fault (I_g) protection, without a time delay. For PowerPacT H- and J-frame circuit breakers, the ZSI function is available only in relation to the upstream circuit breaker (ZSI out). For PowerPacT L-frame circuit breakers, the ZSI function is available in relation to the upstream circuit breaker (ZSI out) and downstream circuit breakers (ZSI in).

Display of Type of Fault

On a fault trip, the type of fault (I_r, I_sd, I_i, I_g), the phase concerned and the interrupted current are displayed. An external power supply is required.

Indicators

Front Indicators

The green “Ready” LED blinks slowly when the electronic trip unit is ready to provide protection. It indicates the trip unit is operating correctly.
Orange overload pre-alarm LED stays on when I > 90% I_r
Red overload LED stays on when I > 105% I_r

Remote Indicators

An SDx relay module installed inside the circuit breaker can be used to remote the following information:

overload trip
overload prealarm (MicroLogic 5 trip units) or ground fault trip (MicroLogic 6 trip units)

This module receives the signal from the MicroLogic electronic trip unit through an optical link and makes it available on the terminal block. The signal is cleared when the circuit breaker is closed.

Note: all the trip units have a transparent sealable cover.

These outputs can be reprogrammed to be assigned to other types of tripping or that protects access to the adjustment rotary switch. The module is described in detail in the section dealing with accessories.

Four Functional Levels

All PowerPacT H-, J-, and L-frame circuit breakers devices can be equipped with the communication function using a pre-wired connection system and a Modbus communication interface module. The interface module can be connected directly or through the front display module (FDM121).

The PowerPacT H-, J-, and L-frame circuit breakers can be integrated in a Modbus communication network. Four functional levels can be used separately or combined to adapt to all supervision requirements.

Level	Function
Communication of status indications	Compatible with PowerPacT H-, J- and L-frame circuit breakers and automatic switches. Use the BSCM module to access the following information: ON/OFF position trip indication fault-trip indication
Communication of commands	Available on all circuit breakers and automatic switches with communicating motor operators, the remote control can be used to: open closed reset
Communication of measurements with MicroLogic 5/6 A or E trip unit	This level provides access to: instantaneous and demand values maximums/minimums energy metering demand current and power power quality
Communication of operating assistance with MicroLogic 5/6 A or E trip unit	This level also provides access to: protection and alarm settings time-stamped histories and event tables maintenance indicators

Modbus Principle

The Modbus RS 485 (RTU protocol) system is an open bus on which communicating Modbus devices (PowerPacT and MasterPacT circuit breakers, Power Meter PM700, PM800, etc.) are installed. All types of PLCs and microcomputers may be connected to the bus.

Number of Devices

The maximum number of devices that may be connected to the Modbus bus depends on the type of device (PowerPacT 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 client, thirty-one servers).

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 client to any Modbus server devices connected to it. The maximum number of active TCP client connections is twelve.

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

IFE Ethernet Interface

IFE Interface, IFE Interface + Gateway Description

IFE Interface

IFE Interface + Gateway

Introduction

The IFE interface and IFE interface + gateway enable low-voltage circuit breakers such as MasterPacT and PowerPacT 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 client Modbus port.

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 mounting 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:

PowerPacT and ComPacT (fixed or drawout) circuit breakers: BSCM communication module
Drawout PowerPacT and ComPacT circuit breakers: BSCM and its respective I/O (Input/Output) application module.

All connection configurations for PowerPacT and ComPacT 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 BSCM.

Once connected, the circuit breaker is considered as a server by the Modbus client. 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 Server 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): 2 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).
