HMCP250W5C - 250Amp Motor Circuit Protector

HMCP250W5C - 250Amp Motor Circuit Protector

When you’re replacing a motor circuit protector, getting the details right matters. The Eaton HMCP250W5C is a 250A, three-pole Series C motor circuit protector designed for applications requiring a J-K frame and a 1250–2500A magnetic trip range. It carries a maximum voltage rating of 600V AC and 250V DC and comes with line and load terminals made from non-aluminum material. For maintenance work on existing equipment, those specifications make it easier to check the part against the original device and determine whether it has the correct form, fit, and function for the application.

Key Features and Benefits

• 250A amperage rating for applications designed around this specific rating.
• Three-pole configuration for compatible motor protection equipment.
• 1250–2500A magnetic trip range provides an important specification to match when replacing an existing unit.
• J-K frame size helps identify the proper form and fit for compatible equipment.
• Part of the Eaton Series C product family.
• Rated for up to 600V AC or 250V DC.
• Equipped with line and load terminals.
• Non-aluminum terminal material matches the manufacturer’s stated construction.

Material Compliance and Certifications

The HMCP250W5C is UL Listed and CSA Certified. Eaton specifies non-aluminum terminal material along with line and load terminals. For replacement applications, these details should be considered alongside the electrical ratings, frame size, dimensions, and equipment documentation rather than relying on the catalog number or amperage rating alone.

Where It Works Best

The HMCP250W5C is best suited to existing motor control and electrical equipment designed for its particular Series C, J-K frame, three-pole configuration. That makes it especially relevant when maintaining legacy equipment where the goal is to replace an existing component while preserving the required form, fit, and function.

Before installation, compare the replacement with the equipment requirements and the part being removed. Key points to check include the 250A rating, 1250–2500A magnetic trip range, J-K frame, three-pole design, 600V AC/250V DC maximum voltage, terminal configuration, and physical dimensions. Those details provide a more complete compatibility check than amperage alone.
