Schneider Electric FA26030AB I Line Circuit Breaker

Schneider Electric FA26030AB I-Line two-pole molded-case circuit breaker delivers 30 A of protection for Square D I-Line panelboards, rated for up to 600 VAC (600 VAC / 250 VDC). This 2-pole device features a line-side I-Line AB connection and load-side lugs, accepts 14-4 AWG aluminum or copper conductors, and provides thermal-magnetic overload protection at 80% rated. With an interrupting capacity of 25 kA at 240 V, 18 kA at 480 V, and 14 kA at 600 V, it is designed to interrupt fault currents safely in commercial and light industrial distribution. The FA26030AB belongs to the FA I-Line family, a type of circuit breaker intended for use in I-Line panelboards and switchboards and specified for applications requiring a 600 V class rating and a 30 A feeder or branch protection. The combination of a compact molded-case body and robust I-Line connection makes it suitable for mounting in compatible Square D enclosures that utilize AB-phase connections, providing reliable, coordinate protection for downstream circuits.
