A circuit breaker (sometimes also called a "circuit breaker") is designed to disconnect an electrical circuit equipped with it in the event of a short circuit or when the current exceeds a certain value.

The operation of a circuit breaker can be based on thermal or electromagnetic principles. It is worth noting that most modern circuit breakers use both of these principles at the same time. How it works is illustrated in Figure 1.

Are you aware that overloads can cause your electrical equipment to be destroyed or damaged, and in rare situations, even a fire? A fuse or MCB is used to safeguard your device against overload. If an electrical circuit is overloaded, a fuse or an MCB will interrupt the flow of power, causing the circuit to short out.

The objective of utilising an MCB or a fuse is the same, however the devices' working principles are different. Both a fuse and a miniature circuit breaker are intended…
