Under voltage coil means it will energized when supply
available, closing coil means it will operate when we are
giving closing command at that time it will operate , shunt
trip means it will operate when we are giving trip command
manually or through fault. CLOSING COIL OPERATE MEANS WE
WILL GET OUTPUT SUPPLY FROM THE ACB TERMINALS , SHUNT TRIP
COIL OPERATE MEANS IT WILL DISCONNECT THE OUTPUT SUPPLY OF
THE ACB TERMINALS. IF UV COIL USED IN ACB MEANS WITHOUT
INCOMING SUPPLY WE CAN'T CLOSE THE ACB.
