MCP431550 - 150Amp Motor Circuit Protector

MCP431550 - 150Amp Motor Circuit Protector

When you’re replacing a motor circuit protector, matching the amperage is only the beginning. The MCP431550 is a 150-amp, 3-pole Type MCP motor circuit protector rated at 600VAC. It uses a magnetic-only trip with an instantaneous setting and a specified 450–1,550 amp trip range. This version also comes with standard aluminum alloy terminals. Put those details together—amp rating, poles, voltage, trip characteristics, terminals, and size—and you have a practical set of specifications for determining whether the MCP431550 belongs in the application.

Key Features and Benefits

• 150 Amp, 3-Pole Design: Gives you two of the first specifications to check when matching an existing motor circuit protector.
• Magnetic-Only Operation: The MCP431550 uses a magnetic trip rather than a thermal-magnetic configuration.
• 450–1,550A Instantaneous Trip Range: A clearly specified range makes it easier to compare the existing application's trip requirements.
• Rated at 600VAC: Suitable for compatible equipment requiring this voltage rating.
• Standard Aluminum Alloy Terminals Included: Terminal material is identified, so you can verify it during the replacement process.
• Built to Last: Solid construction is suited to its intended electrical use when the protector is properly selected, installed, and maintained.

Where It Works Best

The MCP431550 makes the most sense when an existing or legacy installation calls for a 150 amp, 3-pole Type MCP motor circuit protector with magnetic-only operation. The required equipment should also match its 600VAC rating and 450–1,550A instantaneous trip range.
