Main technical parameters

product overview

MV+MN overvoltage and undervoltage release device

Action characteristics:

When the main circuit voltage is (85%~110%) Ue, the release should be able to maintain long-term operation of the circuit breaker. When the voltage of the main circuit rises to (280V ± 5%) or falls to (170V ± 5%), the release combined with the circuit breaker should act to drive the circuit breaker to open. Undervoltage protection interval: (35%~70%)Ue
