Product FAQs
5 answersWhich legacy panelboards are compatible with the CA3175S1 circuit breaker?
This C-Frame unit is specifically designed to fit into older Westinghouse CDP, FDP, and Pow-R-Line panelboards that require a unit mount configuration.
What type of wiring configuration is required for the CA3175S1?
As a unit mount, feed-thru breaker, it requires a cable-in, cable-out wiring setup. The included lugs accept 3 AWG to 300 kcmil aluminum or copper conductors.
Will this Eaton breaker replace my original Westinghouse CA3175S1?
Yes. Eaton acquired the Cutler-Hammer and Westinghouse legacy product lines. This breaker is a direct replacement for the original Westinghouse and Cutler-Hammer CA3175S1 models.
Are the thermal and magnetic trip settings adjustable on this model?
No. The CA3175S1 features a fixed thermal-magnetic trip unit, meaning the long-time and instantaneous (LI) protection parameters cannot be modified in the field.
Can I use an EHD or FD series breaker instead of the CA3175S1?
While facilities often transition to EHD3175 or FD3175 frames for modern upgrades, maintaining existing legacy switchgear typically requires this specific CA-style C-Frame profile to ensure a proper fit without panel modifications.
