2.1 Motor Operating Mechanism

Schematic Diagram

Function

Suitable for remotely closing, tripping (resetting) the circuit breaker,and for automated applications.

Position indication for O (OFF), I (ON), and TRIPPED.

Enables free trip operation of the circuit breaker.

Allows manual or automatic closing and opening of the circuit breaker.

Automatic closing or tripping can be achieved using momentary pulse signals or maintained signal control.

Reliable closing and tripping of the circuit breaker is ensured only when the control voltage is **≥85% and ≤ 110%** of the rated control

voltage (Un).

2.2 Manual Handle Assembly

Function

Employs a unique design and transmission mechanism to perform circuit breaker Closing, Tripping (Reset), and Opening operations via handle rotation.

Features isolated position indication.

Clear position indications: O (OFF), I (ON), and TRIPPED

The breaker in the OFF position accepts 1-3 padlocks (Φ5-8mm), preverhting inadvertent closure and locking compartment access.

In the ON (closed) position, handle rotation mechanically prevents compartment door opening.(For emergency door access, use the handle’smanual override release).

Standard shaft length: 150mm.
