Square D FA-32020 I-Line Circuit Breaker 3P 3PH

The Square D FA32020 I-Line circuit breaker is a 3-pole, 20-amp, 240-volt molded‑case breaker designed for FA‑series panels with I‑Line bus connections. This 3P device uses a thermal‑magnetic trip mechanism to provide reliable overcurrent protection and is built for I‑Line plug‑in mounting with ABC phase connections, enabling quick replacement in compatible equipment. It protects three‑phase circuits in commercial and industrial electrical distributions, making it suitable for feeders and branch circuits that power motors, conveyors, compressors, and other 240‑V, three‑phase loads. Key specifications include model FA32020, 240 VAC rating, 20 A current rating, 3-pole configuration, I‑Line mounting, and FA family construction, with UL/CSA listings typical for Square D components. When selecting a breaker for a 240‑V, 3‑phase installation, the FA32020 provides compatible protection within FA‑series panels and is designed for use in industrial or commercial power distribution where standardization with other FA I‑Line breakers is desired.
