What is difference b/w fuse and breaker?..

Answer / chreamz

A fuse is a normally closed protective device that ionises
(burnout open circuitry) under fault condition or when
current over its rating flow through it. Everything happens
automatically with no external actuator. Once blown, it
must be replaced. A circuit breaker if also a protective
device that gets a closing/tripping command from the relay.
It has internal & external devices (actuator) that bring
about execute the action sent by the relay. The life span
of the CB depends on the load, operation and maintenance.
