Product FAQs

8 answers
Can I use the Eaton GHB3025 to replace an older Westinghouse GHB breaker?

Yes. Eaton acquired the Westinghouse electrical distribution business. The modern Eaton or Cutler-Hammer GHB series serves as a direct, exact-fit replacement for older Westinghouse breakers bearing the same GHB3025 catalog number.

What types of enclosures and panels accept this breaker?

The GHB3025 is designed for use in Eaton Series C panelboards, Pow-R-Line panelboards, switchboards, and compatible motor control centers. It bolts directly to the bus, ensuring a secure, vibration-resistant connection.

What does the "Star" or "480Y/277V" rating mean for installation?

The "Star" (or Wye) rating indicates this breaker is engineered for solidly grounded electrical systems supplying 480V line-to-line and 277V line-to-neutral. It is not rated for use on ungrounded 480V Delta systems.

Is the GHB3025 strictly for AC electrical systems?

No, it is also rated for direct current. While commonly used in alternating current setups, it provides a 14 kA interrupting capacity for 125/250 Vdc circuits, making it highly adaptable for specialized control or DC distribution.

Can I adjust the trip curve for the long-time or instantaneous functions?

No, the GHB3025 features a non-interchangeable, fixed thermal-magnetic trip unit. Both the 25-ampere overload protection and the short-circuit instantaneous trip points are set at the factory and cannot be field-adjusted.

What wire types are compatible with the terminal lugs?

The factory-installed pressure lugs accept both bare copper and aluminum (Cu/Al) conductors. They accommodate a wide range of wire sizes from 10 AWG up to 1/0 AWG, providing flexibility for different field wiring layouts.

Does the GHB3025 include ground fault or arc fault protection?

No, this is a standard thermal-magnetic molded case circuit breaker. It is engineered strictly for equipment and circuit overcurrent and short-circuit protection, without any built-in arc fault or ground fault life safety features.

Are G-frame breakers like the GHB3025 interchangeable with F-frame breakers?

No. G-frame breakers have distinct physical dimensions, mounting hardware, and bus connections compared to F-frame breakers. You must install the specific breaker frame designated by your panelboard label.

    Used model

    Breaker ohm tested out fine and currently working on load test with a longer term battery charger. So far so good. Packaged very well no visible damages during shipping. Even received a follow up call from customer that I missed.

    Good Product, but Disappointed With the Service

    Good product, but I was disappointed with the service. I accidentally placed two separate orders and ended up paying freight on both. I had requested that they combine the orders, and had that been done with the freight waived, it would have saved me money.

    Other than that, everything was good. I’m just disappointed that no one communicated this to me.
