Undervoltage Trip (MN)

This function opens the circuit breaker via an electrical order.

It is made up of:

Instantaneous trip
Fixed undervoltage trip (time delayed) or,
Adjustable undervoltage trip (time delayed)

As shown in the wiring diagram for the remote tripping function below, the delay unit (installed outside the circuit breaker) may be disabled by an emergency off button to obtain non-delayed opening of the circuit breaker.

The undervoltage trip (MN) instantaneously opens the circuit breaker when its supply voltage drops to a value between 35% and 70% of its rated voltage.

If the undervoltage trip is not energized, it is impossible to close the circuit breaker, either manually or electrically. An attempt to close the circuit breaker produces no movement of the main contacts. Closing is allowed when the supply voltage of the undervoltage trip reaches 85% of rated voltage.

Spring-Charging Motors (MCH) for P-Frame Circuit Breakers

The spring-charging motor automatically charges the spring mechanism for closing the circuit breaker and also recharges the spring mechanism when the circuit breaker is in the ON position. Instantaneous reclosing of the circuit breaker is thus possible following circuit breaker opening. The spring-mechanism charging handle is used only as a backup if auxiliary power is absent.

The spring-charging motor is equipped as standard with a limit switch contact (CH) that signals the charged position of the mechanism (springs charged).

Ground-Fault Interface Module

The ground-fault interface module (P-frame, R-frame and NS630b–NS3200 circuit breakers only) is used to sum the current flow in three-phase, four-wire systems and multiple-sourced systems, using one or more specially-designed external current sensors to measure current flow. The ground-fault interface module is commonly used in two applications:

For a ground-source return ground-fault sensing (SGR) system
For a modified differential ground-fault (MDGF) system

More complex systems are possible, for information about these, contact a field sales representative.

Order kit number S48891.

External Sensor for SGR or MDGF Protections

For use on 400 A sensor or higher.

In SGR applications, an external sensor is installed around the connection of the transformer neutral point to ground. Its secondary is connected to the MicroLogic 6.0A, 6.0P or 6.0H trip units.

In MDGF applications, a sensor is installed on each phase and neutral conductor. The sensors for each circuit breaker are connected to an interface module. These, in turn, connect to the MicroLogic 6.0A, 6.0P or 6.0H trip units.

Order kit number S33579.

Sensor Plugs

Sensor plugs are used to set the current rating (I_n) of the PowerPacT P- and R-frame circuit breakers.

Beginning in January 2007 (date code 07011), the sensor plugs are field-replaceable, down to 50% of the original rating. Mechanical keying in the circuit breaker prevents changing a rating plug to a higher rating than the original factory-installed sensor plug.

M2C Programmable Contacts

The M2C contacts are used with the MicroLogic P and H control units, and indicate the type of fault and instantaneous or delayed threshold overruns (i.e: trip unit protection pickup, current/voltage unbalance, under/over voltage, reverse power, phase rotation, under/over frequency, and load shedding). The M2C has two programmable contacts while the M6C has six. They require an external 24 Vdc power supply (100 mA consumption).

NOTE: The M2C uses the same 24 V power supply as the trip unit. The M2C and trip unit power supply must be separate and isolated from the power supply used for the BCM. They may be programmed:

With instantaneous return to the initial state
Without return to the initial state
With return to the initial state following a delay

Zone-Selective Interlocking (ZSI)

ZSI is used to reduce the stress on electrical distribution equipment during fault conditions by reducing the time it takes to clear the fault, while maintaining system coordination between overcurrent protective devices.

During a short-circuit or ground-fault condition on a ZSI system, the device directly ahead of the fault sends a signal upstream via control wiring to restrain upstream circuit breakers from tripping and then trips with no intentional time delay to clear the fault. Upstream devices which receive a restraint signal obey their short-time and/or ground-fault delay settings to maintain coordination in other areas of the system. Upstream devices that do not receive a restraint signal trip with no intentional time delay.

Fault 1—The upstream circuit breaker (A) will clear the fault with no intentional delay, regardless of its time-delay setting.
Fault 2—Circuit breaker (B) will inform upstream circuit breaker (A) that it is clearing the fault. This will prevent circuit breaker (A) from tripping instantaneously. Circuit breaker (A) will trip at the end of its time delay setting if the fault is not cleared during this time.

ZSI requires trip settings be coordinated so a downstream circuit breaker will trip before an upstream circuit breaker under overload, short-circuit or ground-fault conditions. Effective coordination requires a system coordination study. See data bulletin 0100DB0501, Short Circuit Coordination for Low-Voltage Circuit Breakers.

Restraint Interface Module (RIM)

The restraint interface module (RIM) is used to allow zone-selective interlocking communications between circuit breakers with old MicroLogic, Merlin Gerin™, or Federal Pioneer trip units and GC series ground-fault relays. For 120 Vac/24 Vdc systems, use catalog number S48890. For 240 Vac / 24 Vdc systems, use catalog number S48895.

Downstream circuit breakers with MicroLogic 2.0A, 5.0A, 5.0P, 5.0H, 6.0A, 6.0P, and 6.0H trip units can restrain up to fifteen upstream circuit breakers with MicroLogic 5.0A, 5.0P, 5.0H, 6.0A, 6.0P, and 6.0H trip units without requiring a restraint interface module. If the number of upstream circuit breakers exceeds fifteen, then a RIM is required.
