SMD69600AG - 600Amp Circuit Breaker

SMD69600AG - 600Amp Circuit Breaker

The SMD69600AG is a 3-pole, 600 Amp thermal-magnetic molded-case circuit breaker built on the SMD800A frame for your commercial and industrial power distribution applications. Designed to provide reliable overload, short-circuit, and ground-fault protection, this breaker features an adjustable trip unit that allows qualified personnel to tailor protection settings to the specific requirements of the electrical system. Adjustable functions include continuous current setting, long-time delay, instantaneous setting, ground-fault pickup, and ground-fault delay, making it easier to coordinate protection between upstream and downstream equipment. With interrupting ratings of 25kA at 600VAC, 50kA at 480VAC, and 65kA at 240VAC, the SMD69600AG is suitable for your installations requiring dependable fault interruption while maintaining compatibility with existing SMD800A frame equipment. Built for long service life, it serves as a form, fit, and functional replacement for compatible SMD6 molded case circuit breaker applications.
