I need some detail of shunt trip mechanism
I need some detail of shunt trip mechanism
(OP)
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!

RE: I need some detail of shunt trip mechanism
"The Shunt Trip provides remote controlled tripping of the circuit breaker. The shunt trip consists of an intermittent rated solenoid with a tripping plunger and a cutoff switch assembled to a plug-in module."

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