HLXD63B450L - 450Amp Circuit Breaker

HLXD63B450L - 450Amp Circuit Breaker

When your existing electrical system calls for a specific breaker, getting the details right matters. The HLXD63B450L is a 450-amp, 3-pole HLD6-A molded-case circuit breaker intended for use with compatible electrical equipment and legacy-system applications. It uses a non-interchangeable trip unit and comes with line- and load-side lugs, giving maintenance teams and electricians a clearly defined configuration to match against existing equipment. For facilities that keep established electrical systems in service, the HLXD63B450L provides the familiar form, fit, and function when this exact breaker configuration is specified. Simply put, it’s a straightforward molded case circuit breaker built to last in the applications it was designed to serve.

Key Features and Benefits

• 450 Amp, 3-pole configuration for compatible electrical systems.
• HLD6-A breaker type helps identify the correct form, fit, and function for a replacement.
• Non-interchangeable trip unit provides the specified trip configuration for this model.
• Line- and load-side lugs are included with the breaker.
• Compact, defined footprint of 7.50"W x 11.00"L x 4.00"D makes dimensional comparison with existing equipment straightforward.
• A practical choice for maintaining compatibility with legacy electrical systems when the original breaker specifications must be preserved.

Material Compliance and Certifications

Specific material-compliance or certification details were not included in the supplied specifications for the HLXD63B450L. Because requirements can vary by installation and application, UL, CSA, RoHS, REACH, or other certifications should not be assumed unless they are confirmed by the product markings or supporting documentation.

Before installation, check the breaker's identification and ratings against the equipment's requirements and applicable electrical codes.

Where It Works Best

The HLXD63B450L makes the most sense in commercial or industrial electrical systems that specifically call for a 450-amp, 3-pole HLD6-A molded-case circuit breaker with these dimensions and interrupting ratings. It's especially relevant when maintaining legacy equipment, where the goal is to match the existing breaker rather than change the system configuration.
