HMCP400K5C - 400Amp Motor Circuit Protector

HMCP400K5C - 400Amp Motor Circuit Protector

The Eaton HMCP400K5C is a 400A, three-pole Series C motor circuit protector designed for motor protection applications requiring a Frame J-K device. It has a 1000–2000A magnetic trip range and is rated for a maximum of 600V AC or 250V DC. For anyone replacing an existing motor circuit protector, those details matter. The unit is also UL Listed and CSA Certified. When you're trying to match an existing HMCP400K5C, it's worth checking the full catalog number, including the frame, poles, voltage, amperage, and magnetic trip range, rather than relying on the 400A rating alone. Properly applied within its specified ratings, this motor circuit protector is built to last.

Key Features and Benefits

• 400A rating for motor protection applications requiring this specific amperage.
• Three-pole design for compatible equipment and installations.
• 1000–2000A magnetic trip range, an important detail when matching an existing motor circuit protector.
• Uses the Frame J-K configuration.
• Part of the Eaton Series C product family.
• Rated for a maximum of 600V AC and 250V DC.
• Equipped with line and load terminals and non-aluminum terminal material.
• Clearly defined dimensions make it easier to check physical fit against an existing installation.

Material Compliance and Certifications

The HMCP400K5C is UL Listed and CSA Certified. The manufacturer's supplied information directs users to contact the manufacturer for additional compliance details. If an installation has specific code, certification, or compliance requirements, those requirements should be checked against the product specifications before installation.

Where It Works Best

The Eaton HMCP400K5C makes the most sense in motor protection applications already designed around its particular specifications. That means installations calling for a 400A, three-pole, Frame J-K Series C motor circuit protector with a 1000–2000A magnetic trip range.

It can also be a suitable form, fit, and functional replacement in compatible legacy equipment when those specifications match the existing device. Before making that determination, check more than the amperage stamped on the unit. Catalog number, frame size, pole count, magnetic trip range, voltage rating, terminal arrangement, and physical dimensions should all conform to the equipment requirements.
