Product FAQs
5 answersWhich panelboards are compatible with the CA2125 circuit breaker?
It is designed to bolt into legacy Westinghouse CDP and FDP distribution panels, as well as Eaton Pow-R-Line panelboards.
What wire sizes are accepted by the lugs on the CA2125?
The factory-installed line and load lugs accept 3 AWG to 300 kcmil conductors. They are dual-rated for both aluminum and copper wiring.
Can the CA2125 replace older Westinghouse circuit breakers?
Yes. The Eaton CA2125 is an exact replacement for the original Westinghouse CA2125. It also serves as a direct substitute for the legacy CC2125. For a modern equivalent, the EHD2125 is the current replacement for this frame.
What does the LI trip function indicate on this breaker?
The LI designation means it features a thermal-magnetic trip unit with Long-Time (L) and Instantaneous (I) protection. The thermal element provides fixed overload protection, while the magnetic element offers fixed short-circuit protection.
How does the CA2125 mount into a panelboard?
It is a unit-mount breaker with a feed-thru connection. This means it bolts directly to the panel chassis or mounting pan and uses lugs on both the line and load sides, rather than plugging onto a busbar.
