• Fuse is an electrical device that self-destructs and stops the current flow in a circuit whenever the current exceeds the predefined value.
• MCBs are resettable circuit protection device that, on the occurrence of faults, stops the current flow in a circuit.
• Miniature Circuit Breakers (MCBs) are electromechanical devices which are used to protect an electrical circuit from an overcurrent. ...
• Unlike a Fuse, MCB does not have to be replaced every time after a fault occurs and it can be reused.
