LXD63B500L - 500Amp Circuit Breaker

LXD63B500L - 500Amp Circuit Breaker

The LXD63B500L is a 500 amp, 3-pole LXD6-A molded case circuit breaker with a non-interchangeable trip unit and both line- and load-side lugs included. For replacement work, that combination of electrical ratings, physical dimensions, and lug configuration gives you several concrete details to match against the breaker already in service. In an existing or legacy electrical system that calls for the same LXD6-A configuration, the LXD63B500L can be evaluated as a form-, fit-, and functional-replacement candidate. The included line and load-side lugs are particularly important when confirming the required connection arrangement. Its solid molded-case construction is built to last in its intended electrical application when the breaker is selected, installed, and maintained correctly.

Key Features and Benefits

• 500 Amp Rating: Rated at 500A for compatible electrical equipment requiring this specific amperage.
• 3-Pole Configuration: Provides the three-pole arrangement specified for matching applications.
• LXD6-A Type: A key identifier to compare with existing breaker markings and equipment documentation.
• Non-Interchangeable Trip Unit: Uses the specified non-interchangeable trip-unit configuration.
• Line and Load-Side Lugs Included: Includes both line- and load-side lugs, providing a clearly defined connection configuration for replacement matching.

Material Compliance and Certifications

No specific material-compliance or certification information was supplied for the LXD63B500L, so do not assume additional listings, certifications, or material-compliance claims from the model number or electrical ratings alone.

Where It Works Best

The LXD63B500L 500A 3-pole molded case circuit breaker is best suited for evaluation in compatible existing or legacy electrical equipment that calls for an LXD6-A breaker with the same 500A rating, three-pole configuration, non-interchangeable trip unit, line and load-side lug arrangement, physical dimensions, and applicable AIC ratings.
