Circuit Breaker Diagram Electromagnet. These electrical components operate cams wheels rollers and latches to charge close and open the breaker. In case of overloading the bimetallic strip bends causing the release of the spring with the movement of latch point and eventually opening of the mcb contacts.
Press the pushbutton to close the circuit breaker. These electrical components operate cams wheels rollers and latches to charge close and open the breaker. When the live wire carries the usual operating current the electromagnet is not strong enough to separate the contacts.
The three parts are.
The basic circuit breaker consists of a simple switch connected to either a bimetallic strip or an electromagnet. If the circuit breaker is equipped with an undervoltage release optional the latter must be energised in order to close the c i r c u i t b r e a k e r except in the case of downstream supply. The spring then keeps the contacts apart. After the fault is repaired the contacts can be.
