Description
Providing reliable overcurrent defense, the Eaton EDH2125 is a 2-pole, 125A molded case circuit breaker. It offers fixed thermal and magnetic trip functions to ensure precise protection. This F-frame component bolts into Eaton Series C panelboards, switchboards, and motor control centers. It effectively replaces the HFD2125 and transitions to the newer PDD22M0125TFFJ model. It provides a robust 100kAIC interrupt rating at 240VAC and is reverse feed capable.Specifications

Product FAQs
5 answersCan the Eaton EDH2125 circuit breaker be reverse fed?
Yes, this breaker is reverse feed capable. It can be safely back-fed in applications where the power source must connect to the load terminals.
What is the difference between Eaton ED and EDH circuit breakers?
The primary difference is the short circuit interrupting capacity. Both share the exact same physical F-frame footprint and accept the same accessories, but the EDH provides a higher 100kAIC rating at 240VAC compared to the standard 65kAIC rating of the ED breaker.
What is the modern Power Defense replacement for the EDH2125?
The EDH2125 transitions to the newer Eaton Power Defense series, specifically the PDD22M0125TFFJ model. The EDH2125 also serves as a direct replacement for the older HFD2125 breaker.
Does the EDH2125 feature adjustable trip settings?
No, this breaker is equipped with a fixed thermal and fixed magnetic trip unit. The long-time overload and instantaneous short circuit protection levels are factory set and cannot be adjusted in the field.
Are accessories interchangeable between the EDH2125 and other Eaton Series C breakers?
Yes, because the EDH2125 is built on the standard F-frame platform, it shares compatibility with most internal and external accessories, such as shunt trips and auxiliary switches, used across the Eaton Series C F-frame lineup.
