miniature circuit breaker or MCB in low voltageelectrical networkIt automatically switches off the electrical circuit during abnormal condition of the network means in over load condition as well as faulty condition.
The fuse is an electronic device, which is used to protect circuits from over current over load Fuse consists of a low resistance metallic wire enclosed in a non combustible material. Whenever a short circuit, over current or mismatched load connection occurs, then the thin wire inside the fuse melts because of the heat generated by the heavy current flowing through it.Therefore, it disconnects the power supply from the connected system.
