Question

On what does the value of MCB or fuse wire depend in a circuit ?​

Answer 1

Answer:

An MCB or miniature circuit breaker is an electromagnetic device that embodies 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. It can be manually switched ON and OFF as similar to normal switch if necessary.

Answer 2

Answer:

miniature circuit breakers

Explanation:

(MCB) are being used in place of fuses as these are switchs that turn off automatically when current in the circuit exceeds the safe limit. When the fault in the circuit is corrected, the MCB can be reset to the ' ON ' position and the circuit gets completed once again
