MCP431550CR - 150Amp Motor Circuit Protector

MCP431550CR - 150Amp Motor Circuit Protector

The MCP431550CR is a 150 amp, 3-pole Type MCP motor circuit protector with a 600VAC rating and magnetic-only operation. Its instantaneous setting has a specified 450–1,550 amp trip range, giving you a concrete trip characteristic to compare with the equipment already in place. When those specifications match the application, the MCP431550CR can be considered a form-, fit-, and functional-replacement candidate 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: Clearly defined electrical characteristics make comparison with an existing MCP straightforward.
• Magnetic-Only Trip: The MCP431550CR uses magnetic-only operation with an instantaneous setting.
• 450–1,550A Instantaneous Trip Range: Provides an important specification for checking the device against the existing application's requirements.
• 600VAC Rating: Matches compatible equipment requiring a 600VAC motor circuit protector.
• Non-Aluminum Terminals Included: This configuration specifically includes non-aluminum terminals, an important detail when matching an existing installation.
• Built to Last: Solid construction suits its intended electrical application when correctly selected, installed, and maintained.

Material Compliance and Certifications

The available product information states that the MCP431550CR includes non-aluminum terminals. It does not identify the exact terminal material or alloy, so describing the terminals more specifically would go beyond the supplied specifications.

Where It Works Best

The MCP431550CR motor circuit protector is a practical replacement candidate for compatible existing or legacy equipment that calls for a 150A, 3-pole Type MCP device with 600VAC, magnetic-only operation, and an instantaneous trip range of 450–1,550A. The included non-aluminum terminals should also meet the application's terminal requirements.
