SHND69120AG - 1200Amp Circuit Breaker

SHND69120AG - 1200Amp Circuit Breaker

The SHND69120AG is a 1200-amp, 3-pole molded-case circuit breaker built on the SND1200A frame. It is intended for use in your compatible commercial and industrial electrical distribution systems, where the original breaker's ratings and dimensions must be maintained. As a thermal-magnetic circuit breaker, it provides both overload and short-circuit protection while offering several adjustable trip functions to help you match the protection requirements of the application.

This breaker includes adjustable settings for continuous current, long-time delay, instantaneous protection, ground-fault pickup, and ground-fault delay. These adjustments allow qualified personnel to coordinate the breaker with other protective devices in the system when needed. The SHND69120AG carries interrupting ratings of 50kA at 600VAC, 65kA at 480VAC, and 100kA at 240VAC, making it suitable for a wide range of power distribution equipment that requires these ratings. It is built to last and is commonly selected as a form-fit-and-function replacement for compatible installations.
