Product FAQs
6 answersDoes the MA3800F frame include a trip unit?
No, the MA3800F is a frame-only unit. A compatible interchangeable trip unit, such as an MA or HMA series thermal-magnetic trip unit, must be purchased and installed separately to complete the breaker assembly.
Are mounting lugs included with the MA3800F breaker frame?
No, mounting lugs are not included with this frame-only unit. Line and load side lug kits must be sourced separately based on your specific wire size and conductor material requirements.
What determines the final amperage rating of the MA3800F?
While the MA3800F frame has a maximum capacity of 800 amps, the final operating amperage is dictated by the interchangeable trip unit installed. You can install compatible trip units rated below 800 amps to match your specific circuit requirements.
Are Eaton and Cutler-Hammer trip units compatible with this Westinghouse frame?
Yes. Because Eaton acquired the Westinghouse molded case circuit breaker line, Cutler-Hammer and Eaton MA-frame trip units are directly interchangeable with this legacy Westinghouse frame.
What type of panelboards accept the MA3800F breaker frame?
This bolt-on frame is designed for installation in legacy Westinghouse, Cutler-Hammer, and Eaton panelboards, switchboards, and motor control centers that accommodate MA-frame molded case circuit breakers.
Can the interchangeable trip unit be swapped while the MA3800F is installed in a live panel?
No. The panelboard must be completely de-energized and locked out before installing or changing the trip unit. Servicing the breaker frame while energized poses severe arc flash and shock hazards.
