The electromagnetic coil of the undervoltage relay is connected in parallel with the protection or detection circuit, and the auxiliary contact is connected in the control circuit. When the circuit works normally, the normally open contact is closed, and when the voltage is low to its set value, the electromagnetic force generated by the electromagnetic system It will be reduced. Under the action of the return spring, the normally open contact is opened, and the normally closed contact is closed, so that the control circuit is powered off, thereby controlling the main circuit to be powered off, and the protection appliance is not damaged under low pressure.
