Wiring Diagram Circuit Breaker Symbol
Miniature circuit breakers are intended to prevent damage to an electrical circuit as a result of excess current. They are designed to trip during an overload or short circuit to protect against electrical faults and equipment failure. MCBs are widely used as isolating components in domestic, commercial, and industrial settings.

Miniature circuit breakers commonly known as MCB, are mechanically operated switches cum circuit protection devices. It is an electro-mechanically operated automatic circuit protection device and is used to interrupt a circuit during overload and short circuits. It can be used as an alternative to fuses for domestic applications.

In the given example it is 20A. MCB rating is very important and be very precise about it. MCB Breaking Capacity: Breaking capacity can be defined as the maximum level of fault current which can be safely cleared. It is written as in numerals like in in example it is 10000. It means it 10000A = 10kA.

An MCB or miniature circuit breaker is an electromagnetic device that embodies a complete enclosure in a molded insulating material. The main function of an MCB is to switch the circuit, i.e., to open the circuit (which has been connected to it) automatically when the current passing through it (MCB) exceeds the value for which it is set.

MCB FULL FORM | MCB SYMBOL | Miniature Circuit Breaker is the full form of MCB. It is used for tripping purpose while circuit connection in overload or short circuit situation. This type of circuit breaker rated current is below 100 Amps. Nowadays people urges MCB in domestic purpose instead of fuses.
