Product FAQs
6 answers
Which panelboards accept the GHB2090 circuit breaker?
This G-frame breaker is designed to bolt into Eaton Pow-R-Line C, Series C, and legacy Westinghouse PRL2 panelboards.
Can the GHB2090 be installed on a 480V ungrounded delta system?
No. The 480Y/277VAC slash rating indicates it must only be used on solidly grounded wye systems. It is not rated for ungrounded or corner-grounded delta systems.
Is the GHB2090 suitable for reverse-feed applications?
Yes. This thermal magnetic breaker does not have line and load markings, making it fully suitable for reverse-feed installations.
Will this breaker replace a legacy Westinghouse GHB2090?
Yes. Eaton acquired the Westinghouse distribution equipment division, and the current Eaton Cutler-Hammer GHB2090 is the direct, exact replacement for the older Westinghouse model.
Does the GHB2090 provide ground fault or arc fault protection?
No. This is a standard thermal magnetic breaker equipped with fixed long-time and instantaneous trip functions for overload and short-circuit protection. It does not include GFCI or AFCI circuitry.
How does the GHB2090 connect to the panelboard bus?
It features a bolt-on connection that fastens directly to the panelboard bus, providing a secure and reliable mechanical connection for commercial and industrial environments.

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.
