Mini Circuit Breakers

Miniature circuit breakers (MCBs) are found in single, double, and four-pole configurations. They can be used to protect both single-phase and three-phase systems. The different types have been developed to suit specific areas of use. 'B'-type MCBs tend to be used in domestic installations. They trip at lower currents and are suitable for the touchy business of inrush current. 'C' and 'D' MCBs tend to be used in commercial and industrial installations. They can handle higher inrush currents operating in those contexts.

There are various reasons why MCBs are better than fuses. MCBs can be reset after they trip, so they do not have to be replaced like fuses do. When a fuse burns out, that's it—there is no more protection. But when an MCB trips, it can be reset, and you are right back in business. You should also be aware that the circuit level of MCBs can often be adjusted.
