What is the main function of an MCB?

MCBs or Miniature Circuit Breakers are electromechanical devices which protect an electrical

circuit from an overcurrent. The overcurrent, in an electrical circuit, may result from short

circuit, overload or faulty design. An MCB is a better alternative to a Fuse since it does not

require replacement once an overload is detected. Unlike fuse, an MCB can be easily reset

and thus offers improved operational safety and greater convenience without incurring

large operating cost.

The principal of operation is simple. An MCB functions by interrupting the continuity of electrical flow through the circuit once a fault is detected. In simple terms MCB is a switch which automatically turns off when the current flowing through it passes the maximum allowable limit. Generally MCB are designed to protect against over current and over temperature faults (over heating).
