FXD63B150 - 150Amp Circuit Breaker

FXD63B150 - 150Amp Circuit Breaker

The Siemens FXD63B150 is a 150 Amp, 3-pole molded case circuit breaker built for use in compatible Sentron FD-frame power distribution systems. It combines a thermal magnetic trip unit with a fixed, non-interchangeable trip design to provide protection from overloads and short circuits in commercial and industrial electrical installations. Rated for systems up to 600VAC, this breaker offers an interrupting capacity of 22kAIC at 600VAC and 35kAIC at 480VAC. Whether you're replacing a worn breaker during routine maintenance or matching the original specifications of an existing installation.
