Schneider Electric FA34100 I-Line Circuit Breaker

Schneider Electric's FA34100 is a 100-amp, 3-pole molded-case circuit breaker designed for 480 V three-phase distribution. This FA-series I-Line MCCB uses ABC phase connections and I-Line plug-on mounting for quick installation in compatible Schneider Electric panels. It employs thermal-magnetic protection with an 18 kA interrupting rating at 480 VAC (25 kA at 240 VAC) and is rated 80% for continuous duty, making it suitable for feeders and branch circuits in industrial and commercial power systems. As a compact, replaceable protection device within Square D distribution equipment, the FA34100 protects circuits up to 100 A in applications such as motor control centers, panel boards, and other 480 V installations where fast tripping and reliable fault isolation are required.
