Description
Part of the legacy C-Frame family, this 150-amp commercial breaker provides reliable thermal-magnetic protection for industrial applications. It installs into older Westinghouse CDP, FDP, and Eaton Pow-R-Line panelboards requiring a bolt-on connection. The X suffix indicates it comes equipped with load terminals only, making it ideal for bus-connected line side installations. Rated for 10kAIC at 240VAC, it serves as a functional equivalent to the EHD3150.Specifications

Product FAQs
7 answersWhat panelboards are compatible with the CA3150X?
This breaker is designed for installation in legacy Westinghouse CDP and FDP panelboards, as well as Eaton Pow-R-Line distribution panels that accept C-Frame bolt-on breakers.
What does the X suffix indicate on the CA3150X catalog number?
The X suffix indicates that the breaker is equipped with load-side lug terminals only. The line side features a bolt-on connection for direct bus mounting in compatible panelboards.
Is the CA3150X interchangeable with the standard CA3150?
No. While both are 150A C-Frame breakers, the CA3150X is a bolt-on breaker with load lugs only. The standard CA3150 is a feed-thru breaker typically equipped with both line and load lugs.
How does the thermal-magnetic trip unit operate on this breaker?
The breaker utilizes a fixed thermal element for overload protection (Long-Time) and a fixed magnetic element for short-circuit protection (Instantaneous). Neither trip point is field-adjustable on this specific C-Frame model.
Are the load lugs on the CA3150X rated for both aluminum and copper conductors?
Yes, the standard load-side terminals are dual-rated for either aluminum or copper wire, accepting conductor sizes from 3 AWG up to 300 kcmil.
What is required to mount the CA3150X into a legacy Westinghouse panelboard?
Because it is a bolt-on branch device, you must use the correct CDP or FDP retrofit connector kit. These kits contain the specific bus links, phase isolators, and mounting hardware required for safe installation.
What frame family does the CA3150X belong to?
It is part of the legacy Cutler-Hammer C-Frame family. When sourcing replacements, ensure your panelboard is configured for C-Frame dimensions, as they differ from newer F-Frame breakers like the FD3150.
