The main difference between MCB, RCCB, and Isolators

 

Isolators are generally used in power system while on the other hand, MCB is the circuit breaker. Isolators are manually-operated device, and on the contrary, the circuit breaker is the automatically-operated device. Isolators cut the portion of the substance when a fault occurs. The other devices like MCB and RCCB operate without any interruption. The circuit breaker is the device of an Automatic circuit breaker or Miniature circuit breaker which trips the entire system and if any fault occurs, MCB is to protect the wires from the damage. Whereas, on the other hand, residual current device protects the life-threatening problems. RCCB detects the leakage current and protects from the electric shock.

So, this is MCB, Isolators and RCCB and the difference between them.
