Description
Built for industrial environments, the Eaton MCP534000 delivers instantaneous short-circuit defense. This 3-pole, 400A motor circuit protector utilizes magnetic-only trip technology to coordinate with motor control centers and combination starters. Sized for NEMA Size 5 starters, this legacy device replaces older Westinghouse installations. For modern upgrades, it is replaced by the HMCP400X5W. Operating up to 600VAC, it features an adjustable magnetic trip range of 2000-4000A.Specifications
