An MCB, or miniature circuit breaker, is a device designed to interrupt an electrical circuit in the event of an electrical hazard by cutting the power to the load. It's an essential piece of kit for keeping people safe from electric shocks and preventing damage to downstream equipment.

Both an MCB and a fuse are designed to interrupt a circuit in the event of a fault. While a blown fuse must be replaced, an MCB can be simply switched back on again when the fault is fixed, saving time and effort.
