Product FAQs
7 answersWhat panelboards are compatible with the ED2125L circuit breaker?
This F-frame breaker is designed for use in Eaton Series C panelboards, switchboards, and motor control centers. It requires the appropriate F-frame mounting hardware or chassis for installation.
Can the ED2125L replace an FD2125L breaker?
Yes, the ED2125L shares the same physical footprint and F-frame dimensions as the FD2125L. However, the ED2125L is rated for a maximum of 240VAC, whereas the FD series is rated up to 600VAC. Ensure your system voltage does not exceed 240VAC before substituting.
Is the ED2125L suitable for reverse feed applications?
Yes, standard Eaton Series C thermal-magnetic F-frame breakers like the ED2125L can be reverse fed.
How does the ED2125L mount into an enclosure?
The ED2125L is a unit-mount, feed-thru circuit breaker. It bolts directly to the mounting pan or chassis using standard F-frame hardware rather than plugging onto a busbar.
Does the ED2125L feature adjustable trip settings?
No, this breaker features a fixed thermal and fixed magnetic (LI) trip unit. It does not have adjustable dials for long-time or instantaneous pickup.
Is the ED2125L interchangeable with legacy Westinghouse or Cutler-Hammer breakers?
Yes, Eaton acquired the Cutler-Hammer and Westinghouse distribution equipment lines. A modern Eaton ED2125L is a direct, exact replacement for legacy Cutler-Hammer or Westinghouse ED2125L breakers.
Does the ED2125L include ground fault or arc fault protection?
No, the ED2125L is a standard thermal-magnetic circuit breaker providing overload and short-circuit protection. It does not include GFCI or AFCI capabilities.
