続した 地絡継電装置。[Scope of claim for utility model registration] A ground fault relay device comprising a switch and a ground fault relay, which includes a total of two signals at both ends of the secondary winding of a zero-phase current transformer on the upper switch side. Connect the switching relay contacts of the first relay that is excited and driven in the event of an abnormality to the two signal lines on the ground fault relay side, and connect the first relay to the normally closed side of the switching relay contacts. , The normally open side is connected to the power supply for excitation of the second relay, which is interposed between the signal lines of the switch, and opens and closes the series circuit between the trip coil for operating the circuit breaker and the relay contact of the second relay. A ground fault relay device connected between the signal lines on the equipment side.
