A breaker and an isolation switch serve different purposes in electrical systems, and they differ in their functions and applications:

The full form of MCB is Miniature Circuit Breaker. It is a kind of electronic switch that functions automatically. It can detect a problem occurring inside a circuit by identifying the extreme amount of current flow in the circuit.

Surge is a transient overvoltage, the spike shown in the above diagram for a short duration is the transient overvoltage, where transient is defined as having a brief time, such as a millisecond or microsecond. Overvoltage is defined as a voltage that is higher than the nominal voltage. We must safeguard our devices against this surge.

With the rapid development of science and technology, power systems play an increasingly important role in our daily lives. In this complex and huge system, the isolation switch is undoubtedly a vital component. It is not only a safety barrier for the power system, but also a key element to ensure the normal operation of the power system.

Molded Case Circuit Breaker or MCCB is an automatic electrical device. It is a type of circuit breaker that protects the circuit from overloading, short circuit and current surges. It is an advanced version of miniature circuit breaker MCB since it operates like one. However, it offers extra features that make it a superior circuit breaker such as remote closing and adjustable trip settings i.e. its current settings and time settings can be adjusted according to our needs.

Circuit Breaker Protects Home from Overload: In addition, it prevents home fires by ensuring that the current is shut off. Overload circuit breakers allow more current to flow than the wires can handle. This can damage the appliance connected to it and may cause it to overheat.
