SND69120A - 1200Amp Circuit Breaker

SND69120A - 1200Amp Circuit Breaker

The SND69120A is a 1200-amp, 3-pole Type SND6 thermal-magnetic molded-case circuit breaker built on a 1200A frame. It provides overload and short-circuit protection for your compatible commercial and industrial electrical distribution systems and is intended as a form, fit, and functional replacement where an SND6 breaker is specified. One feature many electricians appreciate is the adjustable trip unit. Instead of a fixed setting, it includes continuous current adjustment, long-time delay, and instantaneous trip functions, making it easier to coordinate protection with the rest of the electrical system. The breaker is built to last and is commonly found in larger switchboards, panelboards, and other high-capacity power distribution equipment. Lug terminals are not included, so compatible lugs will need to be supplied separately if required for your installation.
