Schneider Electric FA32015U 15A 240V 3P Circuit Breaker

Sch Schneider Electric's Square D FA32015U is a 15A, 3-pole, 240V molded‑case circuit breaker (MCCB) in the FA family, designed for I‑Line mounting on compatible distribution panels. It provides thermal‑magnetic protection for three‑phase circuits and uses line‑side I‑Line connections with load‑side lugs for straightforward integration, accepting 14–4 AWG copper or 12–4 AWG aluminum conductors. The FA32015U is rated for 240 VAC with an interrupting capacity up to 25 kA at 240V (18 kA at 480V), making it suitable for protection against short circuits in moderate to high fault environments. This FA series breaker is commonly used in commercial and light industrial power distribution to protect feeders and equipment in panels that accommodate FA devices.
