POWER DISTRIBUTION APPARATUS FOR SEPARATE ELECTRICAL OVER CURRENT AND SHORT CIRCUIT PROTECTION

摘要

A system for protecting electrical power distribution circuits and loads electrically connected thereto comprises a circuit breaker or fuse in series with an over current protection device, for example a virtual circuit breaker. The circuit breaker or fuse provides protection against a short circuit condition, and the virtual circuit breaker provides against excess current. Separating the two protection means enables providing a higher current allowance for loads connected to outlets on a branch circuit.
