Fuse is a safety device which is used to limit the current in an electric circuit.use of Fuse protect the appliance from getting damaged .
Circuit breaker i.e MCB, miniature circuit breaker is used in place of a fuse now a days.the use of MCB is more convenient bcoz we don't have to connect a new fuse wire in place it burns and it is quicker to response if current exceeds it's limit in a circuit.
Idolaters....... I don't know sorry.

It isolates the part of the circuit in which the fault takes place from the main supply. It is used in high voltage devices such as transformers, etc. Isolators block the DC signals and allow the AC signals to pass. Circuit Breaker is a protecting device which acts as a switch.
