Schneider Electric FAP34050 BU Circuit Breaker

Schneider Electric’s Square D FAP34050 BU Molded Case Circuit Breaker is a 3-pole protective device rated for 480 VAC operation with a 50 A continuous current rating and an 18 kA short‑circuit interruption rating at 480 VAC. As a molded‑case breaker, it provides overcurrent protection for three‑phase feeders and equipment in industrial and commercial 480 V distribution schemes. The FAP34050 BU is the 50 A/3‑pole variant associated with Square D’s FA/FAP family, a lineage known for compact form factors and dependable performance in panelboard and switchgear assemblies designed for 480 V systems. With an 18 kA interrupting capacity, this breaker supports high‑fault‑current environments typical of modern industrial power networks, helping ensure selective tripping and protection coordination when paired with upstream devices. This model is suitable for retrofit or new installations requiring a 50 A, 480 V, three‑phase protection solution in compatible Square D/Schner Electric panel boards and distribution gear, delivering reliable fault protection without compromising space in the control and distribution enclosures.
