MN Undervoltage Release

MN Undervoltage Release opens the circuit breakers when its supply voltage drops to a value below 35% of rated voltage Un.
●Undervoltage tripping: combined with an emergency-off button, provides fail-safe tripping;
●If the supply voltage is between 0.35 and 0.7 Un, opening is possible, but not guaranteed. Above 0.7 Un, opening does not take place;
●The MN release is continuously supplied if supply is interrupted: either voluntarily through loss of power or faulty wiring;
●The MN release provokes opening circuit breaker;
MN/UVR was designed and developed by Merlin Gerin in early 2000, now it is newly marked as Schneider without any change.
