SHLD69600NT - 600Amp Circuit Breaker

SHLD69600NT - 600Amp Circuit Breaker

Finding the right replacement breaker starts with matching the original equipment. The SHLD69600NT is a 600 amp, 3-pole molded case circuit breaker built on the SLD600A frame and equipped with a SHLD6-A thermal magnetic trip unit. It's intended as a form, fit, and functional replacement for compatible electrical distribution systems, making it a practical choice for maintenance, repairs, and ongoing support of existing equipment.

What makes this breaker especially useful is its adjustable trip unit. Instead of being limited to fixed protection settings, qualified personnel can adjust the continuous current setting, long-time delay, instantaneous trip, short-time pickup, short-time delay, and short-time I²t pickup to coordinate with the needs of the electrical system. That flexibility can simplify system coordination while helping protect connected equipment from overloads and short circuits.

With interrupting ratings of 35kA at 600VAC, 65kA at 480VAC, and 100kA at 240VAC, the SHLD69600NT is commonly found in commercial buildings, industrial facilities, manufacturing plants, and other heavy-duty power distribution applications. It is built to last and should always be installed in equipment verified to be compatible with its ratings and frame size. Lug terminals are not included with this breaker.
