Abstract

Electrical apparatus capable of transmitting to an operating organ the presence of differential currents in electrical utilization installations, characterized in that it comprises balanced electromagnetic means connected to the input of the power supply, capable of producing a resultant non-zero magnetomotive force that is verified by a imbalance, although small, between the currents of the conductors of the circuit of use, suitable means to relieve such magnetomotive force to send a control signal proportional to the magnetomotive force, suitable means to reveal such magnetomotive force and to send an amplified signal to a threshold cutting device to cancel this state of cut and allow the circuit closure of a battery with a control or protection signaling operator.
