Product FAQs
6 answersWhat panelboards are compatible with the CA2150?
It is engineered for unit mounting in classic Westinghouse CDP, FDP, and Pow-R-Line panelboards.
Will this Eaton CA2150 replace my original Westinghouse CA2150?
Yes. Eaton acquired the Westinghouse distribution equipment line and continued producing the CA frame. The Eaton, Cutler-Hammer, and Westinghouse CA2150 units share the exact same physical dimensions and functional ratings.
What does a feed-thru unit mount mean for installation?
A feed-thru unit mount breaker bolts directly to the enclosure backpan rather than plugging onto or bolting directly to a common busbar. Installers must run separate cables to both the line and load side lugs.
Are line and load lugs included with this breaker?
Yes, standard mechanical lugs are included on both ends. They are rated to accept 3 AWG through 300 kcmil aluminum or copper conductors.
Can the thermal magnetic trip unit be adjusted in the field?
No. The CA2150 features fixed thermal and fixed magnetic trip points. The long-time and instantaneous protection thresholds cannot be modified by the installer.
Can I use the CA2150 in a 480V distribution system?
No. The maximum voltage capacity for the CA frame is 240VAC. Connecting it to a 480V or 600V system violates electrical codes and safely exceeds its interrupting capabilities.
