A circuit breaker does the same thing as a fuse — it opens a circuit as soon as the current climbs to unsafe levels — but you can use it over and over again. Advertisement The basic circuit breaker consists of a simple switch, connected to either a …
switch is initially closed along with the circuit breaker. So when contacts C 1, C 2 and C 3 are closed, the current flows through trip coil of circuit breaker. This activates the trip coil which opens the circuit breaker. As auxiliary switch is mechanically coupled with the circuit breaker, it also gets opened. This interrupts the current ...
