Description

Built for heavy-duty commercial environments, this 175-amp thermal-magnetic breaker utilizes a quick-make, quick-break mechanism for reliable operation. It mounts into legacy Westinghouse and Eaton F-Frame panelboards requiring a cable-in, cable-out configuration. The unit comes standard with line and load lugs to facilitate straightforward wiring. When maintaining older switchgear, engineers rely on this specific C-Frame profile as an alternative to the ED3175 or FD3175.

This C-Frame breaker is designed to mount into legacy Westinghouse and Eaton F-Frame panelboards. It requires a cable-in, cable-out configuration.

Is the Cutler-Hammer CA3175 still in active production?

No, the CA3175 is an obsolete, legacy molded case circuit breaker. When maintaining older switchgear, engineers often rely on this specific C-Frame profile, though it has been largely superseded by the ED3175 and FD3175 series.

How is the CA3175 breaker mounted in a system?

It is a unit-mount, feed-thru circuit breaker. It comes standard with line and load lugs to facilitate straightforward wiring for cable-in, cable-out installations.

What wire sizes are accepted by the standard lugs on the CA3175?

The standard line and load lugs accept aluminum or copper wire ranging from 3 AWG to 300 kcmil.

What type of trip mechanism does the CA3175 utilize?

It features a thermal-magnetic trip unit providing fixed long-time and instantaneous (LI) protection. The breaker also utilizes a quick-make, quick-break mechanism for reliable operation under fault conditions.

Can the CA3175 be used to replace an original Westinghouse breaker?

Yes. Eaton and Cutler-Hammer continued the legacy Westinghouse distribution equipment lines. The CA3175 serves as a direct replacement for original Westinghouse CA3175 breakers in existing installations.
