Product FAQs
7 answersWhich Eaton panelboards are compatible with the GHB1030BP24 circuit breaker?
This G-frame breaker is designed to bolt into Eaton Pow-R-Line 2 (PRL2, PRL2a, PRL2X) and Pow-R-Line 3 (PRL3, PRL3a, PRL3X) panelboards.
What does the BP24 suffix mean in the GHB1030BP24 catalog number?
The BP24 suffix indicates that the breaker is originally packaged by Eaton in a bulk pack of 24 units. The breaker itself is electrically and physically identical to the standard GHB1030.
Is the GHB1030BP24 a direct replacement for older Cutler-Hammer GHB breakers?
Yes, Eaton acquired Cutler-Hammer and continues to manufacture the Series C GHB line to the same physical and electrical specifications. An Eaton GHB1030BP24 will directly replace an older Cutler-Hammer GHB1030.
Can this 1-pole breaker be used in a 3-phase panelboard?
Yes, 1-pole GHB breakers can be installed in 3-phase Pow-R-Line panelboards to supply 120V or 277V single-phase branch circuits, provided the panel is rated for the system voltage.
Can the GHB1030BP24 be used in direct current applications?
Yes, this thermal magnetic breaker is rated for up to 125VDC with a 14kAIC interrupting capacity, making it suitable for specific DC control circuits and distribution panels.
What type of trip unit is installed in the GHB1030BP24?
It features a non-interchangeable, fixed thermal magnetic trip unit. This provides both long-time thermal overload protection and instantaneous magnetic short-circuit protection.
Does the GHB1030BP24 require special mounting hardware?
As a bolt-on breaker, it requires standard mounting hardware to secure the line side to the panelboard bus. It does not snap into place like plug-on alternatives.

- MWMARK W.Verified BuyerReviewingEaton / Cutler-Hammer GHB1020 - 20A 1 Pole Molded Case Circuit BreakerRated 3 out of 5 stars7/21/26Good 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.
