What is meant by common trip as it relates to a 2 or 3 pole breaker?

How can we help you today?

Issue:

Does a handle switch trip both breakers?

Product Line:

Miniature Circuit Breaker

Resolution:

This means the 2 or 3 poles are linked internally and if any pole trips, they all open together.

Single pole breakers linked externally with a handle tie are not common trip. One breaker (pole) tripping does not trip the others.
