The simplest form of overcurrent protection is a fuse. Fuses can only be used once and the maximum current that a fuse can interrupt is limited. Thus fuses are only used in low voltage systems and in some medium voltage systems. High voltage systems use a protective system consisting of circuit breakers, current transformers and protective relays instead.
