Square D PFA34030G U Circuit Breaker 3-Pole 30A 600V

The Square D PFA34030G U is a plug‑in circuit breaker built for I‑Line busway installations, delivering 30 A across three poles in a 3‑wire, 480 V AC configuration. Mounted on Square D’s F‑frame platform, this bus plug is designed to drop into compatible busway enclosures to protect feeders and subfeeds within industrial power networks, offering standard thermal‑magnetic trip behavior typical of molded‑case breakers. Suited for modular power distribution, it matches ongoing I‑Line infrastructure in commercial and light‑industrial facilities that rely on Square D busway systems for fast, maintainable protection of motors, conveyors, and other equipment. The PFA34030G U is specified for 480 VAC operation with a 30 A rating and three‑pole, three‑wire configuration, and is listed for use in configurations that support high short‑circuit interrupting performance when installed in compatible busway assemblies. This plug‑in unit is designed to simplify installation and replacement within an I‑Line setup, helping maintain consistent protection across a scalable, modular distribution topology.
