SLD69300G - 300Amp Circuit Breaker

SLD69300G - 300Amp Circuit Breaker

The SLD69300G is a 3-pole, 300-amp thermal-magnetic molded-case circuit breaker built on the SLD600A frame and designed for use in your commercial and industrial electrical distribution systems. Engineered for dependable circuit protection, this breaker provides overcurrent and short-circuit protection while offering multiple adjustable trip settings to help you match application requirements. Its adjustable continuous current, long-time delay, instantaneous, ground-fault pickup, and ground-fault delay functions allow experienced personnel to fine-tune protection for coordinated system operation. With interrupting ratings of 25kA at 600VAC, 35kA at 480VAC, and 65kA at 240VAC, the SLD69300G is well suited for maintaining and servicing compatible existing electrical systems where proper form, fit, and function are essential. Built to last, this breaker is supplied without lug terminals, allowing users to configure terminations as required for the installation.
