SHND69120A - 1200Amp Circuit Breaker

SHND69120A - 1200Amp Circuit Breaker

If you're replacing a 1200 amp molded case circuit breaker, the SHND69120A is built to match the form, fit, and function of compatible SND1200A frame installations. This 3-pole thermal magnetic circuit breaker is commonly used in commercial and industrial electrical distribution systems where dependable overload and short-circuit protection is required.

One thing that makes this breaker especially useful is its adjustable trip unit. Instead of being locked into factory settings, qualified technicians can adjust the continuous current setting, long-time delay, and instantaneous trip to better coordinate protection with the rest of the electrical system. That flexibility can be important in facilities where equipment loads and protection requirements vary.

The SHND69120A carries interrupting ratings of 50kA at 600VAC, 65kA at 480VAC, and 100kA at 240VAC, making it suitable for a variety of high-capacity distribution applications. Whether it's installed in a switchboard, panelboard, or other power distribution equipment, it's designed to provide the protection expected from a thermal magnetic molded case breaker.

This breaker is built to last and intended as a form, fit, and functional replacement for compatible equipment. Please note that lug terminals are not included, so compatible lugs must be supplied separately if required for your installation.
