MCP431800R - 150Amp Motor Circuit Protector

MCP431800R - 150Amp Motor Circuit Protector

For the MCP431800R, start your replacement selection with the details that determine whether the device fits the existing equipment. This 150 amp, 3-pole Type MCP motor circuit protector is rated at 600VAC and operates with a magnetic-only trip. Its instantaneous setting has a specified 575–1,800 amp trip range, and this configuration includes standard aluminum alloy terminals. When your amperage, pole count, voltage, trip characteristics, terminal requirements, and dimensions match the application, the MCP431800R can serve as a form, fit, and functional replacement for compatible existing or legacy equipment. Its solid construction is built to last when selected, installed, and maintained correctly.

Key Features and Benefits

• 150 Amp, 3-Pole Configuration: Provides clearly defined electrical characteristics for accurate replacement matching.
• Magnetic-Only Trip: The MCP431800R uses magnetic-only operation, an important characteristic to confirm against the existing motor circuit protector.
• 575–1,800A Instantaneous Trip Range: Provides a specific trip range to compare with application requirements.
• 600VAC Rating: Suitable for compatible equipment requiring the supplied 600VAC voltage rating.
• Standard Aluminum Alloy Terminals Included: Terminal material is identified in the supplied specifications, removing one more unknown during replacement evaluation.
• Built to Last: Solid construction suits its intended electrical application when properly selected, installed, and maintained.

Material Compliance and Certifications

The available product information specifically states that the MCP431800R includes standard aluminum alloy terminals. No conductor range, terminal size, lug configuration, or other terminal specifications were supplied, so verify those details separately when relevant to the installation.

Where It Works Best

The MCP431800R motor circuit protector is best considered for compatible existing or legacy electrical equipment requiring a 150 amp, 3-pole Type MCP device with magnetic-only operation. The application should also correspond with its 600VAC rating and specified 575–1,800A instantaneous trip range.

For replacement work, review the full specification set. Check the 150A rating, three poles, Type MCP designation, magnetic-only trip, instantaneous trip range, standard aluminum alloy terminals, and 4.13"W x 6.00"H x 3.38"D dimensions against the device being replaced and the requirements of the equipment.
