Schneider Electric FA34030 Molded Case Circuit Breaker

Square D by Schneider Electric FA34030 is a 3-pole molded-case circuit breaker (MCCB) rated for 480 V AC and 30 A, part of the FA (F-frame) family. This 3P FA-series MCCB provides thermal-magnetic overcurrent protection for three-phase feeders in commercial and light-industrial panelboards, and is designed to fit FA-series enclosures and accessories used in Schneider Electric distribution systems. The FA34030 represents the standard 30 A, 480 V, 3-pole configuration; variants within the FA family include shunt-trip versions for remote trip control, such as FA340301021. In practical terms, this MCCB is used to protect three-phase circuits feeding equipment like motors, pumps, and processing gear in panels where 480 V three-phase power is present, delivering reliable interruption when fault current exceeds the set rating while maintaining compatibility with Square D/Schneider Electric protection schemes. The FA34030 is compatible with FA-series protection components and common FA/LA panel configurations, making it a straightforward choice for integrating three-phase overcurrent protection within established Schneider Electric distribution architectures.
