Schneider Electric FA34050 I Line Circuit Breaker

Schneider Electric FA34050 I-Line molded‑case circuit breaker, 50 A, 480 V, 3-pole, FA Series 2, I-Line, thermal‑magnetic trip, with an 18 kA interrupting rating at 480 VAC and 80% continuous‑load capability, designed for fast, secure plug‑in installation in Schneider Electric I‑Line bus systems. This three‑pole unit protects 3‑phase circuits in industrial power distribution, such as feeders to motors, transformers, and other equipment, in commercial and light‑industrial environments operating at 480 VAC. The FA34050 uses ABC phase connections and is built on the FA I‑Line frame (F‑frame family), ensuring compatibility with FA‑series panels and accompanying bus bar arrangements. As part of the FA Series 2 lineup, it provides reliable overload and short‑circuit protection for 3‑phase circuits up to 50 A, making it a compact, robust choice for main distribution panels or subpanels where precise coordination and durability matter.
