FXD63B110L - 110Amp Circuit Breaker Description
FXD63B110L - 110Amp Circuit Breaker
The Siemens FXD63B110L is a 110 Amp, 3-pole molded case circuit breaker from the SENTRON FD family with a thermal-magnetic trip unit. Rated for 600VAC, it provides an interrupting capacity of 22kAIC at 600 volts and 35kAIC at 480 volts. Those ratings aren't just numbers on a specification sheet—they indicate the level of available fault current the breaker is tested to safely interrupt when installed within its published ratings.
If you're matching an existing installation, details like the frame size, trip characteristics, and lug configuration matter just as much as the amp rating.

Installation should be completed by qualified electrical personnel in accordance with applicable electrical codes and manufacturer recommendations.
Where It Works Best
The FXD63B110L is frequently found in switchboards, panelboards, feeder circuits, manufacturing facilities, warehouses, commercial buildings, and other industrial electrical distribution systems that use Siemens FD-frame circuit breakers. The factory-installed TA1FD350A line and load lugs make it a practical choice where the specified copper or aluminum conductor ranges are required without adding separate lug kits.
