CIRCUIT BREAKERS

Circuit breakers are designed to be a resetable electrical circuit interruption device. Two main types are overload and inertia.
The overload variety as the name suggests take the place of a standard fuse and are resetable.
An inertia switch is used as an engine cut-out device and are usually fitted in the fuel system. In the event of an accident the inertia switch cuts the fuel supply thus stopping the engine and minimising fuel spillage.
