The MCCB of type NSX (all ratings till 630 A) can be supplied with MN release coil
its main function is under voltage protection to the MCCB (it protects the CB from undervoltage case that could happen to the supply of the MCCB)
The MN (under voltage release coil) operates if the supply input voltage to the MCCB decreased till it reach 0.7 Un and trip the CB
It doesn't close the CB again until the Supply voltage increase above 0.85 Un (to make sure that the under voltage situation is finished)
