Circuit breaker is used to break the power supply from
loads like switch, but it also protects loads from over
current, short circuit and earth fault.
Types of Circuit breakers as follows:-
MV
1.Air Circuit Breaker (ACB)
2.Vaccum Circuit Breaker (VCB)
3.Oil Circuit Breaker
4.SF6 Circuit Breaker
LV
1.Air Circuit Breaker (ACB)
2.Moulded Case Circuit Breaker (MCCB)
3.Earth Leakage Circuit Breaker (ELCB)
4.Miniature Circuit Breaker (MCB)
5.Motor Protection Circuit Breaker (MPCB)
