FXD63B175L - 175Amp Circuit Breaker Description
FXD63B175L - 175Amp Circuit Breaker
The Siemens FXD63B175L is a 175 Amp, 3-pole FD-frame molded case circuit breaker intended for use in compatible Siemens Sentron electrical distribution equipment. It uses a fixed thermal magnetic trip unit to protect circuits from overloads and short circuits while matching the original electrical characteristics of the installation.
If you're replacing an existing FD-frame breaker with the same ratings, the FXD63B175L is intended to fit the original installation without changing the panel layout or conductor arrangement.
