The Eaton HMCP250W5W is a 250-ampere, Molded Case Circuit Breaker from Eaton's HMC series, specifically engineered as a Motor Circuit Protector. This device integrates the functions of a high-breaking capacity circuit breaker and a motor short-circuit protector into a single unit. It is designed to provide instantaneous magnetic trip protection against short-circuits specifically for motor circuits, but it typically does not include thermal overload protection. The overload protection is usually provided by a separate thermal overload relay in the motor starter combination.
