Schneider Electric FA32015BU Circuit Breaker

FA32015BU is a Schneider Electric Square D molded‑case circuit breaker (MCCB) in the FA frame, rated for 240V AC and 15A across three poles for 3P panelboard protection. This FA I‑Line device uses a thermal‑magnetic trip to provide overcurrent protection for three‑phase loads and is designed with a line‑side I‑Line connection and load‑side lugs for straightforward integration in compatible panelboards. The unit measures about 6 in high by 4.13 in long and 4.5 in wide, and it accepts 14–4 AWG aluminum or copper conductors on the load side. The FA32015BU is specified for 240V operation with a nominal interrupting rating of 10 kA at 240 VAC and 5 kA at 250 VDC, making it suitable for moderate‑to‑heavy commercial or industrial circuits that require reliable three‑phase protection. This 3P MCCB is part of Square D’s legacy FA line, intended for installations that demand robust short‑circuit protection and rugged construction, while remaining compatible with panelboards designed for FA‑series devices. Typical applications include protection for motors, compressors, and other three‑phase equipment powered from 240V systems, where the ampere rating and thermal‑magnetic trip provide prompt disconnection under fault conditions.
