CMH36800 – FEDERAL PIONEER 3P800A 600V 25kA BREAKER

Federal Pioneer's CMH-series MCCBs are considered obsolete or hard-to-find through standard distribution channels. Northern Breaker Group specializes in exactly this — we maintain stock of legacy Federal Pioneer breakers and can often source the CMH36800 when others cannot. Contact us for availability and lead time.

Yes — the CMH36800 is rated 800A at 600V with a 25kA interrupting rating, making it suitable for use as a main or feeder breaker in commercial and industrial switchboards and panelboards that accept the CMH frame, provided the equipment's bus rating and short-circuit withstand rating are compatible. Always verify with your equipment manufacturer's specifications.

Federal Pioneer offered several MCCB frame sizes — the CMH frame is a higher-ampacity frame designed for ratings up to 800A at 600V. It differs from smaller frames (such as the NC or NE series) in physical size, bolt-on pattern, and interrupting capacity. If you are replacing an existing FP breaker, confirm the frame designation on your current unit or panel to ensure a direct fit — our team can help cross-reference.
