Description
Part of the Series C HMCP family, this 7A motor circuit protector provides dedicated short-circuit defense for industrial applications. The Eaton MCP0358R utilizes a magnetic-only trip unit, allowing separate thermal overload relays to handle standard motor starting currents without nuisance tripping. It integrates perfectly into Westinghouse and Cutler-Hammer motor control centers. Operators can fine-tune the instantaneous protection using the adjustable magnetic trip range of 18A to 58A.

    Excellent service

    The breaker was the exact fit. The old would trip when it was put under load. Now it’s back to normal.
