HLXD63B600 - 600Amp Circuit Breaker

HLXD63B600 - 600Amp Circuit Breaker

When your existing electrical system calls for an HLXD63B600, getting the details right matters. This 600-Amp, 3-pole HLD6-A molded-case circuit breaker has interrupting ratings of 35 kAIC at 600 VAC, 65 kAIC at 480 VAC, and 100 kAIC at 240 VAC. It uses a non-interchangeable trip unit and comes with load-side lugs. Rather than relying on amperage alone, buyers should compare the complete part number and specifications with the breaker being replaced. For the right application, the HLXD63B600 delivers the form, fit, and function needed to keep existing equipment in service—and it’s built to last for its intended use.

Key Features and Benefits
