Description

Part of the legacy F-Frame series, this Eaton 30A motor circuit protector is designed for dedicated motor control applications. It provides instantaneous short-circuit protection when paired with a motor starter and overload relay. This bolt-on unit installs into older Westinghouse motor control centers, serving as an exact replacement for aging infrastructure. For modern upgrades, it crosses over to the HMCP030H1. Rated for 18kAIC at 240V, it features an adjustable 90-270A magnetic trip.
