SHLD69500NGT - 500Amp Circuit Breaker

SHLD69500NGT - 500Amp Circuit Breaker

When your electrical system calls for dependable overcurrent protection, the SHLD69500NGT molded case circuit breaker delivers the ratings and adjustable protection needed for many commercial and industrial applications. Built on the SLD600A frame, this 500 amp, 3-pole thermal magnetic circuit breaker is designed as a form, fit, and functional replacement for compatible installations, making it a practical solution when maintaining existing power distribution equipment.

One feature that sets this breaker apart is its Type SHLD6-A adjustable trip unit. Rather than relying on fixed protection settings, qualified personnel can fine-tune multiple trip functions—including long-time delay, instantaneous protection, short-time pickup and delay, continuous current settings, and ground fault protection—to better match the needs of the electrical system. This added flexibility can help coordinate protection across connected equipment while supporting safe and reliable operation. Built to last and engineered for demanding electrical environments, the SHLD69500NGT offers the electrical ratings required for many distribution systems, including 35kA at 600VAC, 65kA at 480VAC, and 100kA at 240VAC.
