ACCESSORIES

SHUNT TRIP COIL
CLOSING COIL
CHARGING MOTOR MECHANISM
When the supply voltage is reduced or below certain value, the device will then trip the breaker.
Supply voltage if reduces or below a value between from the range of 35 - 75 %, the UVT coil will then trip the breaker
instantaneusly. If the supply voltage recover above 75%, the breaker will stil remain as close.
When shunt trip coil is energized, the breaker will trip instantaneously.
When closing release is charged, this device activates closing mechanism ACB can be closed.
The closing spring is charged by electrical motor automatically. For breaker’s remote operation, Closing Coil and Shunt
Trip coil are required. Automatic recharging of closing spring makes fast operations of the O-C-O cycles.
