Operating at 25 amps, this three-pole Series C breaker supplies essential long-time and instantaneous fault protection for commercial facilities. The rugged F-Frame construction ensures durability across heavy-duty electrical distribution networks. Engineered for bolt-on installation, it mounts into compatible Eaton switchboards and panelboards. Rated to interrupt 14kA at 480VAC, this non-interchangeable trip unit is fully HACR and HID rated for specialized lighting and HVAC applications.
What panelboards are compatible with the EHD3025 circuit breaker?
The EHD3025 is designed for Eaton Series C panelboards, switchboards, and motor control centers. It fits panels configured for F-frame breakers, such as the Pow-R-Line 3a (PRL3a) and Pow-R-Line 4 (PRL4), when installed with the correct connector kits.
Are Cutler-Hammer and Eaton EHD3025 breakers the same?
Yes. Eaton acquired Cutler-Hammer and manufactures the Series C EHD3025 under the Eaton brand. They are physically and functionally identical and can be used interchangeably in the field.
Can the EHD3025 be used in DC electrical systems?
Yes, this breaker is rated for up to 250VDC with a 10kAIC interrupting capacity. This makes it suitable for specific direct current applications in addition to its standard AC ratings.
Can I replace an EHD3025 with an FD3025 or HFD3025?
Yes, Eaton F-frame breakers like the FD and HFD share the exact same physical dimensions as the EHD series. The FD and HFD models offer higher interrupting ratings. You can safely install a breaker with a higher AIC rating, but you must not downgrade if your system fault current requires the higher rating.
What type of wire can be used with the EHD3025 load terminals?
The standard load lugs on the EHD3025 accept 14 to 1/0 AWG wire and are rated for both copper (CU) and aluminum (AL) conductors. Always apply the specific torque value printed on the breaker label during installation.
Does the EHD3025 support reverse feeding?
Yes, Eaton Series C F-frame circuit breakers, including the EHD3025, are suitable for reverse feed applications.
