Assembled circuit breakers can be created by adding a trip unit and rating plugs (electronic only) to a circuit breaker frame. Example: Cat. No. 140U-K3X3 + 140U-KTL3-D40 + 140U-KRP3-D35
§ Interrupting ratings shown are for 400V and 480V, respectively. The complete range of ratings can be found in the frame rating table on Breaker Frames.
