Minimum voltage release MN 400V AC SE SPA-MN4A Systeme Electric

Minimum voltage release MN causes immediate tripping of the SystemePact ACB circuit breaker when its supply voltage drops to a value between 35% and 70% of the rated voltage. If the release is not powered, manual or electrical closing of the circuit breaker is impossible. Reclosing the circuit breaker is possible when the release supply voltage reaches 85% of the rated value (formerly Schneider Electric MASTERPACT ACC 33673).
