Hi,

 

Please help me to know the proper way of insering NO/NC/Trip auxiliry contacts for a circuit breaker, also I need to add a Undervoltage/ shunt trip release and a motorized electrical operating mechanism for the same breaker. Now Iam choosing a relay NO contact and change the family to CB. I dont know how to show the undervolatge release/shunt trip release/ motorized operating mechanism for that breakers. While making a component wirle list I need to get all the wire connections associated with that particular breaker. 

 

Regards,

Rajesh.

Under the breaker/disconnect menu in the Insert Component dialog, there is a sub menu for Circuit Breaker 2nd poles.

This includes the standard auxiliary contacts which should cover your contacts.

 

However the the shunt trip and and motorised operator are not represented. I actually copied the standard relay coil, modified it to be a child component and stuck it in this menu as well. This coil is what I use for things like the shunt trip. For a motor, go to the Motor Control section and there should be a suitable motor there.

 

I find that I use coils like this a fair bit as the company I work for builds and supplies 11kV and 33kV vacuum and gas circuit breakers.
