回路。~ In the control power supply monitoring circuit of a protective relay device that operates when the control power supply voltage applied to the protective relay device is equal to or higher than a predetermined value and returns when it is less than a predetermined value, any operation and reset voltage value can be set. Two sets of auxiliary relays are provided in parallel to the control power supply circuit, the first auxiliary relay circuit is connected to a contact that opens when the second auxiliary relay operates, and the second auxiliary relay circuit is connected to the second auxiliary relay circuit. A resistor for providing a holding current to the second auxiliary relay is connected in parallel to a series circuit consisting of a contact that closes when the first auxiliary relay operates and a contact that opens when the second auxiliary relay operates. A control power supply monitoring circuit for a protective relay device characterized in that the circuit is connected to the power source.
