LXD63B450L - 450Amp Circuit Breaker

LXD63B450L - 450Amp Circuit Breaker

The LXD63B450L is a 450 amp, 3-pole LXD6-A molded case circuit breaker equipped with a non-interchangeable trip unit and both line- and load-side lugs. For replacement work in your existing or legacy electrical equipment, matching the breaker to the application is what counts. With line- and load-side lugs included, connection configuration is another clearly defined specification you can check before installation. When the amperage, poles, electrical ratings, dimensions, trip configuration, and lug requirements all match, the LXD63B450L can be evaluated as a form, fit, and functional replacement candidate. Its solid molded-case construction is built to last in its intended electrical application when selected, installed, and maintained correctly.

Key Features and Benefits

• 450 Amp Rating: Rated at 450A for compatible electrical equipment requiring this specific amperage.
• 3-Pole Configuration: Three-pole construction provides an important specification for matching the breaker to existing equipment.
• LXD6-A Type: Clearly identified as an LXD6-A breaker, making it easier to compare against existing equipment documentation and component markings.
• Non-Interchangeable Trip Unit: Uses the specified non-interchangeable trip configuration for applications requiring this breaker arrangement.
• Line and Load-Side Lugs Included: Includes both line- and load-side lugs, providing a clearly defined connection configuration for compatibility checks.

Material Compliance and Certifications

No specific material-compliance or certification information was provided for the LXD63B450L. Certifications or compliance standards should therefore not be assumed from the part number, LXD6-A type, electrical ratings, or molded case circuit breaker classification.

Where It Works Best

The LXD63B450L 450A 3-pole molded case circuit breaker is best for compatible existing and legacy electrical equipment that requires the same LXD6-A type, 450 amp rating, three-pole configuration, non-interchangeable trip unit, AIC ratings, physical dimensions, and line/load-side lug configuration.
