Trip circuit supervison function for Air circuit breakers
Trip circuit supervision is not possible with Masterpact breakers because the coils used are not magnetic but electronic.
Supervision is not possible with these types of coils because of electronic component inside the coil,which makes it difficult to achieve supervision function.
But Please note that the MX coils can be supplied continuously without damage and can withstand a permanent trip-signal.
The MX coil can sustain continuous voltage supply due to internal electronic circuit. So no need for this function as the durability of trip coil is already high.
