EOCR Monitoring Relay Voltage 3-Phase Panel/Din-Rail PMR-220N7

EOCR MCU 3-Phase Monitoring Relay, Voltage Range: 160-300VAC, Output: 1 SPDT (Normally Energized), 50/60 Hz, Panel / DIN-Rail Mount, Supply: 220VAC.

As the instantaneous power-out restart relay, it enables the restart of a motor that has been stopped as a result of instantaneous power-out (within 0.5 ~ 5 seconds) in the power system or voltage sag without the need to take any action after power supply is resumed. It is designed to enable start after the Time Delay to prevent the motors connected to all systems from starting at a time after power supply is resumed. It prevents the possible stoppage of processes due to the instability of the power system.
