LD63B600L - 600Amp Circuit Breaker

LD63B600L - 600Amp Circuit Breaker

The LD63B600L is a 600A, 3-pole molded-case circuit breaker for equipment that requires an LD-frame breaker with a 600V rating. The breaker is rated at 40°C and meets UL 489 and IEC 60947-2 standards. The LD63B600L is well suited to replacement work when the original installation calls for the same frame, amperage, voltage, interrupting capacity, lug arrangement, and physical dimensions. When you properly select, install, and operate it within its specified ratings, it's built to last in its intended application.

Where It Works Best

The LD63B600L is a practical choice when you're maintaining equipment that already calls for a 600A, 3-pole LD-frame breaker with the same electrical and physical requirements. It's especially useful in legacy installations where keeping the correct form, fit, and function matters more than simply finding another breaker with a 600A nameplate.
