LMXD63A800 - 800Amp Motor Circuit Protector

LMXD63A800 - 800Amp Motor Circuit Protector

No lugs installed. That’s one of the first things to notice about the LMXD63A800, especially if you have an existing breaker in front of you and you’re trying to confirm a match. This is an 800A, three-pole LMD-frame molded case circuit breaker with a thermal-magnetic, non-interchangeable trip. Properly matched, installed, and maintained within its stated ratings, the LMXD63A800 is built to last.

Key Features and Benefits

• No lugs installed: Easy to overlook, but important. Connection hardware needs to be checked separately for the application.
• 800A, three-pole setup: Two basic specifications you can quickly compare with the breaker already in service.
• LMD frame: Helps narrow the fit when working with compatible existing or legacy equipment.
• Non-interchangeable trip: The trip arrangement is fixed rather than interchangeable, making this a useful identification point.
• Thermal-magnetic design: Matches the trip-unit type stated for the LMXD63A800.
