SLD69600NT - 600Amp Circuit Breaker

SLD69600NT - 600Amp Circuit Breaker

The SLD69600NT is a 600-amp, 3-pole thermal-magnetic molded-case circuit breaker designed for use in your commercial and industrial electrical distribution systems that require dependable overcurrent and short-circuit protection. Built on the SLD600A frame, this breaker is intended as a form, fit, and function replacement for compatible installations, making it well-suited for maintaining or servicing existing electrical equipment. Its adjustable trip unit allows users to fine-tune multiple protection settings, including continuous current, long-time delay, instantaneous pickup, short-time pickup, short-time delay, and short-time I²t pickup, helping you to coordinate system protection for a wide range of applications. Constructed to withstand demanding operating environments, this breaker is built to last while delivering the electrical ratings and compatibility required for legacy power distribution systems. Please note that lug terminals are not included with this circuit breaker.
