Schneider Electric FA32040 I-Line Circuit Breaker

The Schneider Electric Square D FA32040 I-Line molded‑case circuit breaker is a 3‑pole, 40‑amp protective device for 240‑V three‑phase circuits. Part of the FA I‑Line family, it uses thermal‑magnetic protection with both long‑time and instantaneous tripping, and is intended for use in F‑Frame I‑Line panelboards. The unit accepts #14–1/0 AWG aluminum or copper conductors on the load side and features a line‑side I‑Line connection with ABC phase wiring. The FA32040 carries an interrupting rating up to 25 kA at 240 V (18 kA at 480 V), making it suitable for distributing power to moderate‑ to high‑demand circuits. Typically deployed in industrial or commercial electrical distributions to protect feeders and branch circuits, the FA32040 is compatible with I‑Line busways and panelboards designed for FA‑series breakers.
