Square D FA24030BC Molded Case Circuit Breaker

Square D FA24030BC is a 2-pole molded-case circuit breaker in the FA I-Line family, rated for 30 A at 480 VAC (also listed for 250 VDC) with a plug-on line-side I-Line connection. It features a BC phase configuration and accepts load-side lugs for 14-4 AWG aluminum or copper conductors, enabling straightforward panelboard wiring. The device uses a thermal-magnetic trip mechanism and offers an interrupting rating of up to 18 kA at 480 VAC (25 kA at 240 VAC) and is 80% rated for continuous duty in ambient temperatures up to 40°C. Designed for FA/I-Line installations, it protects 480 VAC feeder or branch circuits in industrial or commercial electrical systems that require reliable short-circuit protection in a compact molded-case form factor. Use of the FA24030BC is appropriate in panelboards or switchboards that specify FA-series I-Line breakers for 480 V service, providing robust overcurrent protection with load-terminal compatibility for aluminum or copper conductors.
