Abstract

A switching apparatus for use in conjunction with a fuse, the switching apparatus including a circuit interrupter having a pair of separable contacts, a sensor for sensing a line fault, and an actuator for moving the contacts to an open state when a line fault is sensed, and wherein the switching apparatus is arranged such that the contacts always return to a closed state.

IPC Classes  ?

• H01H 85/00 - Protective devices in which the current flows through a part of fusible material and this current is interrupted by displacement of the fusible material when this current becomes excessive
• H01H 75/00 - Protective overload circuit-breaking switches in which excess current opens the contacts by automatic release of mechanical energy stored by previous operation of power reset mechanism
• H01H 71/04 - Means for indicating condition of the switching device
• H01H 75/04 - Reset mechanisms for automatically reclosing a limited number of times
