The Schneider Electric FA34050BU is a three‑pole molded‑case circuit breaker in the FA (I‑Line) family, rated for 50 A at 480 V. It uses a thermal‑magnetic trip unit (non‑interchangeable) to protect three‑phase circuits from overload and short‑circuit conditions. This FA‑series device is designed for use in distribution panels where compact form and reliable overcurrent protection for 480 V systems are required.
