SDX and SDTAM Modules for MicroLogic Trip Units

SDx and SDTAM are relay modules with two outputs. They send different signals depending on the type of fault. They may not be used together.

SDx Module

SDx module with terminal block.

The SDx module remotely monitors the trip or alarm conditions of PowerPacT H-, J-, and L-frame circuit breakers equipped with electronic protection.

An SDx relay module installed inside the circuit breaker can be used to remote the overload trip signal.

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. These outputs can be reprogrammed to be assigned to other types of tripping or alarm.

The SDx module may be used in 400 Hz systems for voltages from 24 to 440 V.

The SD2 output, available on all MicroLogic trip units, corresponds to the overload-trip indication.

The SD4 output, available on MicroLogic 5/6, is assigned to:

overload pre-alarm (MicroLogic 5)
ground-fault trip indication (MicroLogic 6)

These two outputs automatically reset when the device is closed (turned ON).

For MicroLogic 5/6, the SD2 and SD4 outputs can be reprogrammed to be assigned to other types of tripping or alarm.

It is possible to assign a function output characteristics:

latching with a time delay. Return to the initial state occurs at the end of the time delay
permanent latching. Return to the initial state takes place through the communication function.

Static outputs: 24–415 Vac / Vdc; 80 mA max.

SDTAM Module

SDTAM module with terminal block

The SDTAM module, linked to the contactor controller, opens the contactor when an overload or other motor fault occurs, thus avoiding opening of the circuit breaker. The SDTAM module is specifically for the motor-protection MicroLogic trip units 2 M (2.2 M and 2.3 M).

MicroLogic 2 M

The SD4 output opens the contactor 400 ms before normal circuit-breaker opening in the following cases:

overload (long-time protection for the trip class)
phase unbalance or phase loss

The SD2 output serves to memorize contactor opening by SDTAM.

Output characteristics

Output reset can be:

manual by a pushbutton included in the wiring diagram
automatic after an adjustable time delay (1 to 15 minutes) to take into account the motor-cooling time

Static outputs: 24–415 Vac / Vdc; 80 mA max. a (+) 24–415 V.

Shunt Trip (MX) and Undervoltage Trip (MN)

A voltage release can be used to trip the circuit breaker using a control signal.

Shunt Trip and Undervoltage Trip

Applications

Shunt Trip (MX)

Trips the circuit breaker when the control voltage rises above 70% of its rated voltage
Impulse type ≥ 20 ms or maintained control signals
AC shunt trips are suitable for ground-fault protection when combined with a Class I ground-fault
Sensing element
Continuous duty rated coil

Undervoltage Trip (MN)

Trips the circuit breaker when the control voltage drops below a tripping threshold
Drops out between 35% and 70% of the rated voltage
Continuous duty rated coil
Circuit breaker closing is possible only if the voltage exceeds 85% of the rated voltage. If an undervoltage condition exists, operation of the closing mechanism of the circuit breaker will not permit the main contacts to touch, even momentarily. This is commonly called “Kiss Free.”

Installation and Connection

Accessories are common to H-, J-, and L-frame circuit breakers and snap into cavities under the front accessory cover of the circuit breaker.
Each terminal may be connected by one 18–14 AWG (1.0–2.5 mm²) stranded copper wire.

Operation

The circuit breaker must be reset locally after being tripped by shunt trip (MX) or undervoltage trip (MN).
Tripping by the shunt trip or undervoltage trip has priority over manual (or motor operator) closing; in the presence of a standing trip order such an action does not result in any closing, even temporarily, of the main contacts.
Endurance: 50% of the rated mechanical endurance of the circuit breaker

Earth Leakage Module (ELM) (H- and J-Frame Only)

J-Frame Circuit Breaker with ELM Installed

The Earth Leakage Module (ELM) is an add-on module which, when connected to a PowerPacT H- or J-frame MCCB, provides low-level ground-fault sensing and ground-fault relay functions.

Because these ELMs are highly sensitive (30 mA to 3 A), they provide much greater protection than GFMs (20 to 200 amperes sensitivity). The ELMs provide greater protection of control circuits and other sensitive equipment. The associated circuit breaker must have a 48 Vdc shunt trip), which may be field-installed (kit S29392) or factory-installed (suffix –SP) in the H- or J-frame circuit breaker.

The add-on Earth Leakage Module (ELM) features:

Adjustable ground-fault pickup levels as low as 30 mA
Adjustable ground-fault time delays from instantaneous to 500 msec (time delay can be applied to any setting)
Integral ground fault push-to-test feature
Ground-fault indicator; pop-up button for local status and contacts for remote indication (to be used only with the tripping option)
All ELMs are supplied for I-Line mounting and are easily convertible to unit-mount by removing the I-Line mounting feet
Three poles; 240 to 600 Vac maximum: 3-phase, 3-wire (no neutral) and 1-phase, 2-wire applications
Line-power obtained through internal bus to provide power for electronics, shunt trip, and integral test feature
A shunt trip is required in the circuit breaker; it may be field-installed or factory-installed in the PowerPacT H and J circuit breakers.

Manual Mechanical Interlocking System

Some installations use two power supply sources to counter any temporary loss in the main supply. A mechanical interlocking system is required to safely switch between the two sources. The replacement source can be a generator set or another network.

Managing multiple power sources can be controlled manually by mechanical interlocks.

The mechanical interlocking system is made up of:

two H-, J-, or L-frame devices (circuit breakers or switches) controlled manually
mechanical interlocking, which prevents handle movement from the OFF position while the other device is in the ON position.

Since it is controlled manually by a maintenance technician, switchover time from the normal source to the replacement source can vary.

Interlocking with Toggle Control (S32614)	Interlocking with Rotary Handles (S32621)

Interlocking of Circuit Breakers with Toggle Control

Two devices can be interlocked using this system. Two identical interlocking systems can be used to interlock three devices installed side by side.

Authorized positions:

one device closed (ON), the others open (OFF)
all devices open (OFF)

The system is locked using one or two padlocks (shackle diameter 0.19–0.31 in. [5 to 8 mm]). This system can be expanded to more than three devices.

There are two interlocking-system models:

one for PowerPacT H- and J-frame circuit breakers
one for PowerPacT L-frame circuit breakers

All toggle-controlled unit-mount or plug-in PowerPacT H-, J-, and L-frame circuit breakers and automatic switches of the same frame size can be interlocked. The devices must be either all unit-mount or all plug-in versions. Interlocking is not available for I-Line constructions.

The toggle interlock system can receive one or two padlocks with diameters of 0.19–0.31 in. (5–8 mm). Both interlocked circuit breakers must be unit-mount or both plug-in. Two sliding interlocking bars can be used to interlock three circuit breakers installed side-by-side, in which case one circuit breaker is in the ON (I) position and the two others in the OFF (O) position. (Kit S29354, not available for two-pole HD and HG devices.)

Interlocking of Two Devices with Rotary Handles

Interlocking involves padlocking the rotary handles on two devices which may be either circuit breakers or automatic switches.

Authorized positions:

one device closed (ON), the other open (OFF)
both devices open (OFF).

The system is locked using up to three padlocks (shackle diameter 0.19–0.31 in. [5 to 8 mm]).

There are two interlocking-system models:

one for PowerPacT H- and J-frame circuit breakers
one for PowerPacT L-frame circuit breakers

All rotary-handle unit-mount or plug-in PowerPacT H-, J-, and L-frame circuit breakers and automatic switches of the same frame size can be interlocked. The devices must be either all unit-mount or all plug-in versions. Interlocking is not available for I-Line constructions.

The rotary handles are padlocked with the devices in the OFF (I) position. The interlock mechanism inhibits the two devices from being closed (ON/I) at the same time, but allows for both devices to be open (OFF/O) simultaneously. (Kit S29369. Not available for two-pole HD and HG devices.)

Interlocking Devices using Keylocks (Captive Keys)

Interlocking with Keys

Interlocking using keylocks makes it possible to interlock two or more devices that are physically distant or that have very different characteristics, for example medium-voltage and low-voltage devices or a PowerPacT H-, J-, and L-frame circuit breaker and automatic switch.

Each device is equipped with an identical keylock and the key is captive on the closed (ON) device. A single key is available for all devices. It is necessary to first open (OFF position) the device with the key before the key can be withdrawn and used to close another device.

All rotary-handle PowerPacT H-, J-, and L-frame circuit breakers and automatic switches can be interlocked between each other or with any other device equipped with the same type of keylock.

For circuit breakers equipped with rotary handles or a motor operator. Interlocking with keys may be easily implemented by equipping each of the circuit breakers, either unit-mount or drawout, with a directly mounted rotary operating handle and a standard keylock, with only one key for the two keylocks. This solution enables interlocking between two circuit breakers that are geographically distant or that have significantly different characteristics.

Use:

A keylock adapter (one required for each circuit breaker)
Two identical keylocks with a single key

See Rotary Operating Handles for more information.

Unit-Mount Circuit Breakers

The standard lugs can be removed for the installation of compression-type lugs or bus connections. All lugs are UL Listed/CSA Certified for their proper application and marked for use with aluminum and copper (Al/Cu) or copper only (Cu) conductors. Lugs suitable for copper and aluminum conductors are made of tin-plated aluminum.

Mounting

H-, J-, and L-frame circuit breakers may be mounted vertically, horizontally or flat on their back without any derating of characteristics.

Unit-mount H- and J-frame circuit breakers are supplied with two mounting screws, unit-mount L-frame circuit breakers are supplied with four mounting screws. These mounting screws are inserted through mounting holes molded into the circuit breaker case and threaded into the mounting enclosure, rails or through the panel door for flush mounting.

A DIN rail mounting bracket (catalog no. S29305) is available for the H- and J-frame circuit breakers.

NOTE: DIN rail mounting is not compatible with motor operated applications.

I-Line Circuit Breakers

PowerPacT H-, J-, and L-frame circuit breakers are available in I-Line construction for easy installation and removal in I-Line applications.

I-Line circuit breakers use “blow-on” type line side connectors. In case of a short circuit, increased magnetic flux causes the plug-on connectors of the circuit breaker to tighten their grasp on the bus bars. The I-Line connectors and circuit breaker mounting bracket are integral parts of I-Line circuit breakers and cannot be removed or replaced. I-Line circuit breakers come with mechanical load side lugs, or optional terminal nut to connect to bus bars or to compression (crimp) lugs.

Plug-In Circuit Breaker Mounting

Plug-In Mounting

The plug-in base is mounted through a panel. The plug-in configuration makes it possible to:

Extract and/or rapidly replace the circuit breaker without having to touch connections
Allow for addition of future circuits at a later date

When the circuit breaker is in the connected position, the primary voltage is fed through the circuit breaker by means of multiple finger disconnects. Control voltage of internal accessories is provided through secondary disconnects.

Parts of a Plug-In Configuration

Plug-in Base: The plug-in base provides mounting through a front panel or mounting on rails.
Disconnects: Provides both primary and secondary disconnect to the circuit breaker.
Safety Trip Interlock: The safety trip causes automatic tripping if the circuit breaker is ON before engaging or withdrawing it; the safety trip does not prevent the circuit breaker operation, even when the circuit breaker is disconnected.
Mandatory short terminal shields.

Disconnecting Blocks

Manual Auxiliary Connector

Accessory circuits exit the circuit breaker using one to three secondary disconnecting blocks (nine wires each). Circuit breaker connection wires for the options installed with trip unit STR53UP exit through the automatic secondary disconnecting blocks. These are made up of:

A moving part connected to the circuit breaker through a support (one support per circuit breaker)
A fixed part mounted on the plug-in base, equipped with connectors for wire up to 14 AWG (2.5 mm²)

For test purposes, circuit breakers may be equipped with one to three manual auxiliary connectors, which allow the auxiliaries to remain connected when in the “disconnected” position.

Plug-In Base (Mounting Options)


Mounting Through a Panel	Mounting on Rails

The L-frame plug-in mounting is Listed under UL file E113555 and Certified under CSA file LR 69561.

Drawout Mounting

The cradle is made up of two side plates installed on the plug-in base and two other plates mounted on the circuit breaker.

The drawout mounting provides all of the functions of the plug-in base, plus:

Disconnected position—the power circuit is disconnected, the circuit breaker is simply withdrawn and may still be operated (on, off, push-to-trip)
Circuit breaker may be locked using 1 to 3 padlocks, diameter 0.19 to 0.31 inch (5–8 mm), to prevent connection.
Auxiliaries can be tested using manual auxiliary connector.

Drawout mounting is on a backplate:

Through a front panel or on rails
Horizontally or vertically

Accessories for drawout circuit breakers:

Auxiliary contacts indicator for installation on the fixed part of the cradle, indicating the “connected” and “disconnected” position
Toggle collar for circuit breakers with toggle through front panel, intended to maintain the degree of protections whatever the position of the circuit breakers (supplied with a toggle extension)
Keylock which can be used to
- Prevent insertion for connection
- Lock the circuit breaker in the connected or disconnected position
Telescopic shaft for extended rotary handles
Control voltage, which is provided through automatic secondary disconnect in the connected position only. Electrical accessories can be tested in the disconnected position with an external wiring harness.

The drawout-mounted cradle is listed under UL file E113555 and certified under CSA file LR69561.

Voltage Takeoff (Control Wire Terminals) for Mechanical Lugs and Terminal Nuts

Mechanical Lug Control Wire Terminal

Busbar Control Wire Terminal

PowerPacT H- and J-Frame mechanical lugs may be equipped with a separate control wire termination. The kit is available factory installed or as a field installable kit. The adaptor is secured underneath the lug and has a tab extension suitable for attachment of a 0.250 inch slip-on connector.

All L-frame mechanical lugs are pre-tapped for control wires. For control wire installation, use an 8–32 x 1/4 in. screw (not provided) into tapped control wire hole in lower left hand corner of the lug.

Fully insulated type connectors must be used to prevent live parts from extending into the wiring gutter area.

Bus-Bar Connections

The H-, J- and L-frame circuit breakers may be equipped with captive nuts and screws for direct connection to bars or to compression (crimp) lugs.

For H- and J-frame, these are readily field-installable, simply by removing the mechanical lug and replacing with the appropriate terminal nut inset described in Factory-Installed Terminal Nut Inserts for Bus or Crimp Lug Connection. They are also available factory-installed, using the Product Selector or by using the catalog suffixes below.

For L-frame, the mechanical lug can be removed, leaving the threaded nut insert intact. This configuration may be ordered with the suffixes described below. Connection hardware (terminal screws) must be ordered as in Factory-Installed Terminal Nut Inserts for Bus or Crimp Lug Connection.
