Schneider Electric FA-14100C Molded Case Circuit Breaker

Square D by Schneider Electric FA14100C is a 100 A, 1-pole molded case circuit breaker (MCCB) designed for 480Y/277V AC distribution. It uses a thermal-magnetic trip mechanism for overcurrent protection and accepts 14–1/0 AWG aluminum or copper conductors on the load side, with a line-side I-Line connection and phase connection C for straightforward wiring. The FA14100C is rated 80% for continuous duty and provides an interrupting capacity of 25 kA at 120/240 VAC and 18 kA at 480Y/277 VAC, supporting short-circuit protection in high-voltage commercial applications. This MCCB protects feeders and branch circuits in 480Y/277V systems and is suitable for applications such as lighting, control circuits, and other single-pole protections in commercial and light-industrial installations.
