SND69800ANT - 800Amp Circuit Breaker

SND69800ANT - 800Amp Circuit Breaker

When you're maintaining an existing electrical distribution system, finding the right circuit breaker means paying close attention to the details. The Siemens SND69800ANT molded case circuit breaker is an 800 Amp, 3-pole, 600V breaker from the Siemens SENTRON family, designed for applications that specify an ND-frame breaker with electronic trip protection. Equipped with Siemens Sensitrip LSI functions, it provides long-time, short-time, and instantaneous protection characteristics for compatible electrical systems. Its interrupting ratings are 25 kA at 600V AC and 50 kA at 480V AC, so verify the voltage rating when selecting the correct replacement.
