MN voltage releases are used to trip the circuit breakers, they serve primarily for remote, emergency-off commands, it is advised to test the system six months.
Circuit breakers controlled by MN: when the circuit breakers have been tripped by an MN release, they must be reset before it can be closed.
MN under voltage opens the circuit breakers when its supply voltage drops to a value below 35% of rated voltage Un: ? Automatic opening of circuit breaker is ensured when the continuous voltage supply to release U?0.35xUn;
? 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;
