shunt trip coil for ACB

[danieldos2572]

What is the function of the shunt trip coil? If I need to replace our shunt trip coil, how can I determine the right size/spect? Thanks

The shunt trip coil trips the breaker open when the coil is energised.
Contact the breaker supplier. You need to get the coil from the breaker manufacturer. They are brand and model specific.

If your shunt trip coil has faulted, take it to a motor rewind company to have it rewound. I have done this many times as most of our switchgear is no longer supported by manufacturer.
