HMCP050K2C - 50Amp Motor Circuit Protector

HMCP050K2C - 50Amp Motor Circuit Protector

The Eaton HMCP050K2C is a 50-amp, three-pole motor circuit protector designed for Series C applications using a J-K frame. It has a 50–500A magnetic trip range and non-aluminum terminal material. If you're replacing an existing HMCP050K2C, those details matter—the amperage rating alone isn't enough to determine whether a motor circuit protector is the right match. Checking the catalog number, frame, pole configuration, and magnetic trip range can help you identify the correct form, fit, and function for the existing equipment.

Key Features and Benefits

• 50A rating for applications designed around this amperage specification.
• 50–500A magnetic trip range for compatible motor protection applications.
• Three-pole configuration for equipment requiring a three-pole protector.
• J-K frame makes it easier to verify compatibility with an existing installation.
• Part of the Eaton Series C product family.
• Non-aluminum terminal material as specified by the manufacturer.

Material Compliance and Certifications

The HMCP050K2C is UL Listed and CSA Certified. The manufacturer specifies non-aluminum terminal material. These details can be important when matching a replacement component to the requirements of existing electrical equipment or a particular installation.

For applications with additional material or regulatory requirements, those requirements should be checked separately before installation.

Where It Works Best

The Eaton HMCP050K2C motor circuit protector is intended for compatible motor protection applications requiring a 50A, three-pole Series C unit with a J-K frame and 50–500A magnetic trip range. It can be particularly useful when maintaining existing or legacy equipment where matching the original component's electrical ratings and physical configuration is important.
