SHND69100A - 1000Amp Circuit Breaker

SHND69100A - 1000Amp Circuit Breaker

If you're replacing a compatible SND 1200A frame circuit breaker, the SHND69100A offers the electrical ratings and adjustable trip functions needed to keep an existing system operating as intended. This 3-pole, 1000-amp molded-case circuit breaker uses a thermal-magnetic trip unit to help protect electrical equipment from overloads and short circuits in commercial and industrial power distribution systems.

What makes this breaker especially useful is the adjustable trip unit. Qualified personnel can set the continuous current, long-time delay, and instantaneous trip functions better to coordinate protection with the rest of the electrical system. That flexibility can be important when matching the breaker to the equipment already in service.

The SHND69100A carries interrupting ratings of 50kA at 600VAC, 65kA at 480VAC, and 100kA at 240VAC, making it suitable for applications requiring those fault-current ratings. Built on the SND 1200A frame, it's intended as a form-fit-and-function replacement for compatible installations. Like many breakers in this series, this one does not include lug terminals; they must be supplied separately if your application requires them.

Built to last, this breaker is commonly used where maintaining an existing electrical distribution system is the priority.
