Product FAQs
6 answersWhat does the S1 suffix indicate on the GHB3015S1?
The S1 suffix designates a factory-installed 120VAC shunt trip. This feature includes a pigtail lead that allows the breaker to be tripped remotely via a control signal for emergency shutdown or automation purposes.
Which panelboards accept this G-frame breaker?
The GHB3015S1 is designed for bolt-on installation in Eaton Pow-R-Line panelboards, Series C panelboards, and compatible legacy Cutler-Hammer or Westinghouse motor control centers and switchboards.
Will this Eaton breaker replace an older Cutler-Hammer GHB3015S1?
Yes. Eaton acquired Cutler-Hammer and continues to manufacture the Series C G-frame line. The modern Eaton GHB3015S1 is a direct, drop-in replacement for legacy Cutler-Hammer and Westinghouse breakers sharing the exact same catalog number.
How does the GHB3015S1 connect to the panelboard bus?
It utilizes a bolt-on connection, fastening directly to the busbar with screws. This provides a secure, vibration-resistant connection required in commercial and industrial Eaton Pow-R-Line panelboards.
Can the GHB3015S1 be back-fed in a panelboard?
Yes, this thermal-magnetic breaker is suitable for reverse feed applications. It can be safely back-fed when required by the specific panelboard or control circuit configuration.
Is the GHB3015S1 suitable for HVAC equipment?
Yes, this 15A breaker is HACR rated, meaning it is certified for use with heating, air conditioning, and refrigeration equipment that requires a 3-pole disconnect with remote shunt trip capabilities.

- 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.
