FXD63B070L - 70Amp Circuit Breaker Description
FXD63B070L - 70Amp Circuit Breaker
The Siemens FXD63B070L is a 70 Amp, 3-pole molded case circuit breaker in the SENTRON FD family. It has a fixed thermal-magnetic trip unit, a 600VAC maximum voltage rating, and standard 40°C calibration. For anyone replacing your existing FD-frame breaker, those details are worth checking one by one. A breaker can look right and still be wrong for the application if the pole count, amperage, voltage, interrupting rating, or trip style does not match. This model is rated 22kAIC at 600VAC and 35kAIC at 480VAC, so it should be matched to equipment that calls for those exact ratings.
