MCCB (Moulded Case Circuit Breaker) is used to protect electrical circuits and equipment from overloads and short circuits.
Functions of an MCCB:
* Overload protection – trips when current is too high for a long time.
* Short-circuit protection – trips instantly during a fault.
* Isolation – can be used to switch power ON and OFF for maintenance.
* Protection of motors, generators, transformers, and distribution panels.
