MCP431800 - 150Amp Motor Circuit Protector

MCP431800 - 150Amp Motor Circuit Protector

Matching a motor circuit protector for your existing equipment means looking beyond the amp rating. The MCP431800 is a 150 amp, 3-pole Type MCP motor circuit protector with magnetic-only operation and a specified instantaneous trip range of 575–1,800 amps. It is rated at 600VAC and includes standard aluminum alloy terminals, giving you several concrete specifications to compare with the unit being replaced. When the complete specification set matches the application, the MCP431800 can be considered a form, fit, and functional replacement candidate. Its solid construction is built to last when the protector is selected, installed, and maintained correctly.

Key Features and Benefits

• 150 Amp, 3-Pole Configuration: Provides clear electrical characteristics for matching an existing MCP installation.
• Magnetic-Only Operation: The MCP431800 uses magnetic-only operation with an instantaneous setting.
• 575–1,800A Instantaneous Trip Range: This specific trip range gives technicians another key specification to check when selecting a replacement.
• 600VAC Rating: Suitable for compatible equipment requiring a motor circuit protector with this voltage rating.
• Standard Aluminum Alloy Terminals Included: The supplied specifications identify the terminal material, helping with a more complete compatibility check.

Material Compliance and Certifications

The available product information states that the MCP431800 includes standard aluminum alloy terminals. No conductor range, terminal size, or additional material specifications were supplied, so those details should be checked separately if they are important to the installation.

Where It Works Best

The MCP431800 motor circuit protector is best considered for compatible existing or legacy electrical equipment requiring a 150 amp, 3-pole Type MCP protector with magnetic-only operation. A proper replacement should also match its 600VAC rating and specified 575–1,800A instantaneous trip range.
