Product FAQs
5 answersWhich panelboards are compatible with the EHD3100 circuit breaker?
This bolt-on F-frame breaker is designed to install into Eaton and Cutler-Hammer Series C panelboards, Pow-R-Line C panelboards, switchboards, and motor control centers.
Can I use this to replace a legacy Westinghouse EHD3100?
Yes. Eaton acquired the Westinghouse distribution equipment line, and the modern Eaton Series C EHD3100 is a direct, drop-in replacement for older Cutler-Hammer and Westinghouse breakers bearing the exact same catalog number.
Is the EHD3100 fully rated for 100A continuous loads?
No, it is a standard 80 percent rated breaker. Per National Electrical Code (NEC) guidelines, continuous loads running for three hours or longer should be kept to 80 amps or less.
Can the EHD3100 be reverse fed?
Yes, Eaton Series C F-frame breakers without interchangeable trip units are suitable for reverse feed applications, as they do not have specific line and load directional restrictions printed on the case.
Is the Eaton EHD3100 breaker HACR rated?
Yes, all Eaton Series C F-frame molded case circuit breakers carry an HACR rating, making them approved for group motor applications like heating, air conditioning, and refrigeration equipment.
