Product FAQs
5 answersCan the GHC1030 be mounted on a standard DIN rail?
Yes, this breaker can be mounted on a standard 35mm DIN rail, but it requires a separate Eaton DIN rail adapter kit. For 1-pole and 2-pole G-Frame breakers, use adapter part number 1225C79G01.
Is the Eaton GHC1030 rated for reverse feed applications?
Yes, all Eaton Series C G-Frame circuit breakers, including the GHC1030, are suitable for reverse feed applications.
Does this 30A breaker carry an SWD rating for switching fluorescent lighting?
No, the SWD (Switching Duty) rating on Eaton G-Frame breakers is only applied to 15A and 20A single-pole models. The 30A GHC1030 does not carry an SWD rating, although it is HACR rated for heating, air conditioning, and refrigeration equipment.
Is there a difference between the Cutler-Hammer GHC1030 and the Eaton GHC1030?
No, they are the exact same molded case circuit breaker. Eaton acquired the Cutler-Hammer and Westinghouse distribution equipment lines, so you may see this G-Frame breaker labeled under any of these three brand names depending on its manufacturing date.
What type of enclosures are compatible with the GHC1030?
This unit mount breaker is designed for use in Eaton Series C enclosures, OEM control panels, and switchboards that accept G-Frame breakers. It is a feed-thru breaker and is not compatible with standard plug-on residential load centers.
