Product FAQs
6 answersWhat does the S1 suffix indicate on the GHB3060S1?
The S1 suffix denotes a factory-installed 120V AC shunt trip. This allows the breaker to be tripped remotely by applying a 120V AC voltage signal to the accessory leads, which is common for emergency stop or load shedding applications.
Which Eaton panelboards will accept this GHB series breaker?
This bolt-on breaker is designed for use in Eaton Pow-R-Line commercial panelboards, specifically the PRL2a and PRL3a models, as well as older Westinghouse Series C panels. It will not fit in standard BR or CH residential load centers.
How do I connect the shunt trip accessory on this unit?
The factory-installed shunt trip features color-coded pigtail wire leads exiting the side of the breaker. These leads must be connected to a normally open push button, switch, or control relay that provides the 120V AC trip signal when activated.
Can I use this breaker on a 480V ungrounded delta system?
No. The 480Y/277V rating indicates it is intended strictly for solidly grounded wye systems where the voltage to ground does not exceed 277V. It lacks a straight 480V rating and is unsafe for delta configurations.
Will this replace older Westinghouse or Cutler-Hammer GHB breakers?
Yes, Eaton currently manufactures these under the same G-frame design. This unit serves as a direct bolt-in replacement for legacy Cutler-Hammer and Westinghouse GHB3060S1 models requiring a 120V shunt trip.
Is this breaker suitable for direct current applications?
Yes, it carries a 125/250V DC rating. When wiring for DC systems, you must follow Eaton guidelines for multi-pole DC switching to ensure proper arc extinguishing.

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.

- 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.
