FXD63B080 - 80Amp Circuit Breaker

FXD63B080 - 80Amp Circuit Breaker

The Siemens FXD63B080 is an 80 Amp, 3-pole molded case circuit breaker from the SENTRON FD family. It features a fixed thermal-magnetic trip unit, an FD frame, and a 600VAC maximum voltage rating. If you're replacing an existing breaker, it's important to match more than just the amp rating. The frame size, interrupting capacity, trip type, and pole configuration all need to be the same to maintain compatibility with the original equipment. This model is rated 22kAIC at 600VAC and 35kAIC at 480VAC, making it a direct form, fit, and functional replacement wherever those ratings are specified.
