Square D Enclosed Circuit Breaker FA-100-AWK Series E1

The Square D FA-100-AWK Series E1 is a robust enclosed circuit breaker designed for industrial and commercial applications requiring reliable overcurrent protection. Manufactured by Square D (now part of Schneider Electric), this enclosure houses F-frame circuit breakers such as FA, FH, or FC types, supporting up to 100A ratings. It features a NEMA 1 indoor-rated metal enclosure with a manual operating handle for on/off/trip/reset functions, ensuring safe isolation and control of electrical circuits. Key benefits include enhanced safety through interlocked operation, preventing access while energized, and durability in harsh environments. Applications span motor control, lighting panels, and power distribution systems. Advantages over similar products include Square D's reputation for reliability, easy installation with provisions for conduit entry, and compatibility with a wide range of breakers. Drawbacks may include its limitation to indoor use (not suitable for outdoor without modifications) and the need for a separate breaker (not included). Based on attached images, the unit appears used with minor cosmetic wear, scratches, and dust, but structurally intact; no visible damage to the mechanism or enclosure. Faceplate details confirm Catalog No. FA-100-AWK, Series E1, with wiring diagrams for 2-3 pole configurations. No parent/child assets noted.
