MN undervoltage release

The MN release opens the circuit breaker when its supply voltage drops to a value below 35 % of its rated voltage Un.

Undervoltage tripping, combined with an emergency-off button, provides fail-safe tripping.

The MN release is continuously supplied, i.e. if supply is interrupted:

either voluntarily, by the emergency-off button,

or accidentally, through loss of power or faulty wiring,

the release provokes opening of the circuit breaker.
