Product FAQs

5 answers
What enclosures and panelboards are compatible with the KD3175 breaker?

This K-frame breaker is designed to mount in Eaton Series C panelboards, Pow-R-Line 3a and 4 panelboards, as well as compatible switchboards and motor control centers.

What is the adjustment range for the magnetic trip on the KD3175?

The KD3175 features an adjustable magnetic trip unit that can be set between 5 and 10 times the continuous ampere rating. For this 175A breaker, the instantaneous short-circuit pickup range is 875A to 1750A.

Can the Eaton KD3175 replace older Westinghouse KD breakers?

Yes, Eaton Series C K-frame breakers are backward compatible. The KD3175 can directly replace legacy Cutler-Hammer and Westinghouse KD3175 breakers with the same 175A rating and 3-pole configuration.

Can the trip unit on the KD3175 be swapped or upgraded in the field?

Yes, the KD3175 features an interchangeable thermal-magnetic trip unit. This allows panel builders to change the continuous ampere rating or trip characteristics without replacing the entire K-frame breaker.

Is the KD3175 circuit breaker suitable for reverse feed applications?

Yes, standard thermal-magnetic Eaton Series C K-frame breakers like the KD3175 are reverse feed capable. Always verify that no voltage is present on either the line or load side before performing maintenance in reverse feed setups.
