徴とする電磁接触器の制御回路。 It has a holding current limiting resistor that is short-circuited at the b contact of the magnetic contactor when it is not in operation, and which is inserted in series with the excitation coil of the electromagnetic contactor by opening the b contact when it is in operation, and an automatic control output contact. In the control circuit of the electromagnetic contactor where the excitation coil is turned on and off when turned on and off, the control coil is connected in parallel with the holding current limiting resistor, and when the holding current limiting resistor is disconnected. The electromagnetic contactor is characterized by comprising an auxiliary relay that operates when the electromagnetic contactor operates and is self-held via the automatic control output contact and opens the excitation circuit of the electromagnetic contactor by its B contact. Contactor control circuit.
