FXD63B125 - 125Amp Circuit Breaker Description
FXD63B125 - 125Amp Circuit Breaker
The Siemens FXD63B125 is a 125 Amp, 3-pole molded case circuit breaker from the SENTRON FD family with a thermal-magnetic trip unit. It is rated for 600VAC and carries interrupting ratings of 22kAIC at 600 volts and 35kAIC at 480 volts. In replacement work, those ratings deserve close attention. A breaker can have the right amp rating and still be the wrong match if the frame, voltage, trip characteristics, or interrupting capacity do not line up with your existing equipment.

Where It Works Best
You’ll typically find the FXD63B125 in compatible switchboards, panelboards, feeder circuits, manufacturing facilities, warehouses, commercial buildings, and other industrial distribution equipment that uses Siemens FD-frame breakers. It is a practical match for maintenance and repair work where the existing system calls for a 125 Amp, 3-pole breaker with the same voltage, interrupting ratings, and trip configuration.
