HMCP400R5C - 400Amp Motor Circuit Protector

HMCP400R5C - 400Amp Motor Circuit Protector

The HMCP400R5C is an Eaton Series C motor circuit protector rated for 400 amps and built for three-phase motor protection. With its J-K frame, three-pole design, and defined voltage and trip ratings, it is a practical replacement when your existing system already uses this Eaton HMCP configuration.

For replacement work, the details are important. The HMCP400R5C has a 1750–3500 amp magnetic trip range, helping protect compatible motor circuits from high-current faults. Its three-pole design protects all three phases with a single coordinated device.

Material Compliance and Certifications

The Eaton HMCP400R5C motor circuit protector is UL Listed and CSA Certified. These listings can be important when replacing components in equipment that requires specific certifications and electrical ratings.

Motor protection equipment should be selected based on the complete application, not amperage alone. Qualified electrical personnel should handle installation and servicing in accordance with applicable codes, equipment instructions, and site requirements.

Where It Works Best

• Motor circuits requiring a 400A motor circuit protector
• Compatible Eaton Series C equipment
• Applications designed for a J-K frame
• Three-phase systems needing a three-pole protector
• Systems operating within the 600V AC or 250V DC maximum rating
• Applications requiring a 1750–3500A magnetic trip range
• Maintenance and replacement work on existing motor control equipment
• Installations where matching the original form, fit, ratings, and terminal configuration matters
