Schneider Electric FA34045 3 Pole Circuit Breaker

Schneider Electric FA34045 is a 3-pole molded-case circuit breaker (MCCB) in the FA I-Line family, rated for 45 A at 480 VAC. It provides thermal-magnetic overcurrent protection, with trip characteristics that respond to overloads and short circuits, and is designed for plug-in I-Line mounting in compatible Schneider Electric panelboards to simplify installation and maintenance. The FA34045 uses line-side I-Line connections and standard phase labeling (ABC) for straightforward wiring and termination of three-phase feeders, supporting common load terminations in industrial power-distribution setups. With a 480 VAC operating rating, this breaker protects main feeders and branch circuits in commercial and light-industrial environments, including motors, pumps, HVAC equipment, and transformers, where compact MCCB protection within an I-Line configuration is required.
