Electic operating mechanism

Electric operating mechanism can be mounted on the front panel of TM2-100 and TM2- 630A circuit breakers , it can realize remote opening，closing adn resetting with 2 or 3 pulses type or self -holding signal , if necessary，the circuit breaker also can realize on-site operation by means of using front panel . Each series of electric operating mechanism module is provided with only one specification that can be applicable for kinds of circuit breakers.

Insert type and with drawable type

insert type and with drawable type:make sure the circuit breaker can be withdrawn or inserted rapidly not need contacting live element , can be used for standby outlet circuit for future extending circuit breaker or connecting wire，besides, can be applied to visual breaking.

Under voltage releasing coils and shunt releasing coils

The following circuit breakers have respective universal under voltage releasing coils(MN) and shunt releasing coils(MX)

TM2-100/TM2-630

TM2-800~1600

When the rated operating voltage steps down to 70%~35% ,the under voltage release (coils) makes the circuit breaker break; when the control voltage is lower than 35% of rated operating voltage, the under voltage release(coils) can prevent circuit breaker closing ; and when the control voltage is more than 85% of rated operating voltage ,the under voltage release(coils) can make sure the circuit breaker closes reliably.

When the supply voltage is more than 70% of rated control voltage， the shunt release (coils) makes the circuit breaker trip and break reliably.

Time belay rotary handle

Time delay rotary handle The time delay rotary handle is mounted for circuit breaker on the switch cabiner, it can be operated with front rotary handle , it has three functions: O (breaking), I (making) and tripping.

Auxiliary switch

TM2 auxiliary switch is provided with only one nodule , applicable for SNM1 full series circuit breakers , has four functions: On/Off(OF), tripping indication (SD), fault display (SDE) and grounding fault display (SDV).

Link accessory

Provided with many kinds of linking types, in cluding bare cable ,fore wire or rear wire for cable lug as well as insertion type or with drawable type wires, furthermore, there are a set of connecting accessories installed for circuit breaker rapidly.
