Product FAQs

7 answers
Is the ED2125 manufactured by Eaton or Cutler-Hammer?

Eaton acquired Cutler-Hammer, so the ED2125 may arrive with either branding. Both are the exact same F-Frame breaker built to identical specifications.

What is the difference between the Eaton ED2125 and FD2125?

Both are 2-pole, 125A F-Frame breakers sharing the exact same physical dimensions. The ED2125 is rated for 240VAC maximum, while the FD2125 is rated up to 600VAC with higher interrupting capacities. An FD2125 can safely substitute for an ED2125.

Which panels are compatible with the ED2125 breaker?

This bolt-on breaker is designed exclusively for use in Eaton and Cutler-Hammer Series C panelboards, switchboards, and motor control centers that accept F-Frame circuit breakers.

What does the ED prefix indicate on this Series C breaker?

The ED prefix identifies this unit as a standard-interrupting F-Frame breaker rated for a maximum of 240VAC, providing a 65kAIC interrupting capacity at that voltage.

Are the lugs on the ED2125 rated for aluminum wire?

Yes, the factory lugs are dual-rated for both copper and aluminum (Cu/Al) conductors. They accept wire sizes ranging from 4 AWG to 4/0 AWG.

How does the trip unit protect the circuit?

The ED2125 utilizes a non-interchangeable thermal-magnetic trip unit. It provides fixed long-time thermal protection against mild overloads and fixed instantaneous magnetic protection to clear severe short circuits.

Can this breaker be used in DC applications?

Yes, the ED2125 is UL listed for direct current circuits up to 125VDC, making it suitable for industrial control and battery systems, with an interrupting rating of 10kAIC at 125VDC.
