shunt trip breaker/E-stop circuit

[hillbilly1]

The multiple wires are used to either incorporate the integral switch that opens when the breaker is tripped, or to bypass-it. If you bypass it, make sure that the trip signal is momentary so that you don't burn up the coil by keeping power on it.

It's actually been found out to be a latching contactor, these type don't look like a regular contactor, because they are low profile to fit inside a panelboard enclosure. they have built in clearing contacts, so constant voltage is Ok.

Sorry but it doesn't.

The Carling device you refer is about 'shunting' around the overload sensing portion of the breaker. It is not about a 'shunt trip' coil as they are normally applied in molded case breakers.

The Carlin unit is wired the SAME way how a shunt trip is assembled. At that moment I could not find an appropriate link to the shunt trip, but if you doubt it I will find it for you.:happyyes:
