    I need some detail of shunt trip mechanism

    Thank you, Busbar! Does this mean shunt trip rating has nothing to do with circuit breaker rating? It actually trip CB by mechanical means?

    I need some detail of shunt trip mechanism

    I know shunt trip using the magnetic field of an energized coil to trip circuit breaker. But how do I know the minimum current through the coil which would have strong enough magentic field to trip a 20 amps CB? Thank you! I am new to this place. Hope can get your help!
