ALSTOM VAGM22AF171G is an instantaneous undervoltage relay. Instantaneous undervoltage relay is an electrical protection device, which is used to quickly cut off the circuit when the power supply voltage is lower than the set value to prevent the equipment from being damaged due to low voltage. The following are some details about the instantaneous undervoltage relay:

principle of operation
When the power supply voltage drops below the set value, the trigger mechanism of the under-voltage relay is activated to cut off the control circuit and make the relay cut off the output circuit, thus protecting the equipment.
Main function
Equipment protection: prevent the equipment from running under low voltage and avoid damage.
Power system safety: to prevent over-current and overheating caused by insufficient power grid voltage, prolong the service life of equipment and ensure the safe and reliable operation of power system.
