INDEPENDENT DEVICE FOR DISCONNECTING POWER SUPPLY SOURCE Russian patent published in 2017 - IPC H02J9/00 

FIELD: electricity.

SUBSTANCE: independent device for disconnecting a power supply source contains an automatic circuit breaker with an independent splitter, NC contacts of the circuit breaker are connected between the outputs of the phase circuits of the supply network and the output terminals for connecting the power consumer' circuits, the first output of the independent release winding is connected to one of the consumer's connection output terminals, and the second output of its winding by the remote control cable is connected to the neutral terminal of the power supply source via a NO contact of the switching element of actuating the control signal of the power supply disconnection, in parallel to which the circuit of the series-connected resistor and indicator is connected.

EFFECT: providing the remote control of the circuit's serviceability while reducing the element base due to the use of a disconnected power supply for supplying control circuits and controlling the disconnection of the power supply source.
