MCP431800RC - 150Amp Motor Circuit Protector

MCP431800RC - 150Amp Motor Circuit Protector

The MCP431800RC is a 150 amp, 3-pole Type MCP motor circuit protector with a 600VAC rating and magnetic-only operation. For replacement work, those basics are important, but they aren't the whole story. When your amperage, three-pole configuration, voltage, magnetic trip characteristics, terminal requirements, and dimensions match the application, the MCP431800RC 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 Rating: Provides a clear starting point when matching the MCP431800RC to the requirements of existing electrical equipment.
• 3-Pole MCP Configuration: The three-pole arrangement and Type MCP designation provide important identifiers for replacement selection.
• Magnetic-Only Operation: Uses a magnetic-only trip, so match this characteristic directly to the existing application's requirements.
• 575–1,800A Instantaneous Trip Range: The specified instantaneous range gives electricians and maintenance personnel another concrete value to check during replacement evaluation.
• 600VAC Rating: Rated at 600VAC for compatible equipment requiring this voltage rating.
• Non-Aluminum Terminals Included: This MCP431800RC configuration includes non-aluminum terminals.

Material Compliance and Certifications

The available specifications state that the MCP431800RC includes non-aluminum terminals. The exact terminal material or alloy is not identified, so describing the terminals more specifically would go beyond the information provided.

No specific UL, IEC, RoHS, REACH, or other certification or material-compliance information was supplied for the MCP431800RC. If the application requires a particular listing, certification, or material standard, confirm that requirement against the appropriate product documentation before selecting the device.

Where It Works Best

The MCP431800RC motor circuit protector is a practical replacement candidate for compatible existing or legacy equipment calling for a 150A, 3-pole Type MCP device with 600VAC, magnetic-only operation, and an instantaneous trip range of 575–1,800A. The application should also be compatible with the supplied non-aluminum terminals.

For a proper replacement match, don't stop at the amperage. Compare the three-pole configuration, voltage rating, Type MCP designation, magnetic trip characteristics, terminal requirements, and physical dimensions with the existing device. The 4.13"W x 6.00"H x 3.38"D footprint is particularly useful when confirming physical fit.
