Question

what is a miniature circuit breaker?

Answer 1

It is a fuse which is use in house.
It is a coil through which , when a high current is passed is melt.As a result circuit is breaker and the current is not transformed.

Answer 2

Explanation:

Miniature circuit breaker :

• The miniature circuit breakers (MCBs) used in our houses are specially made switches that turn off the circuit when the current exceeds the predefined value.
• They may make use of the magnetic effect (like a circuit breaker) or heating effect (with a bimetallic strip) of a current.
• They are available for different current values (amperes) and hence, can be used in different sections of the circuit.
• For example, There maybe one for the circuit of a bedroom and another for the kitchen.
• The main advantage of an MCB is that it can be reset, just like a switch, and hence can be used many times without having to be replaced.
• It's disadvantage over a fuse is that it is more expensive.
