APARATO PARA INTERRUMPIR CORRIENTES DE FUGA EN UN SISTEMA ELECTRICO.

摘要

A circuit interrupter having an associated control system which senses overload current or ground fault current and causes an appropriate tripping of the circuit interrupter. Tripping energy for causing the circuit interrupter to open under a normal fault condition is derived from the fault current itself. In addition, tripping energy for causing the circuit interrupter to open due to a ground fault condition is derived from the ground fault current.
