application shunt trip for mccb
(OP)
hi all,
i want to know more specificly about how to install and operate shunt trip for mccb (low voltage cb). because so far, i only ever seen mccb operating by handle (manually).we use hand to rotate that mccb. and for ACB, i have known that ACB can operate by push the button to open/close the tripping coil.
my question is can we operate mccb automaticly like we do to ACB? may be use shunt trip?
thank you

We use quite a few of them for isolating equipment under emergency shut down conditions.

Siemens offers an external accessory on their VL Series MCCBs which is essentially the same as the charged energy closing system on ACBs that can close the breaker remotely. It has a pull handle to charge the spring or it can be done with a small motor.
