It delivers thermal‑magnetic trip protection with an 18 kA interrupting rating at 277 VAC and uses line‑ and load‑side lug terminals for direct feed‑through connections. The FAL series is intended for single‑phase distribution in commercial or industrial panels, allowing a protected circuit to feed through to a second panel while maintaining protection on the original branch. This 277 V, 20 A FAL14020 unit from Schneider Electric (Square D) is suitable for controlling lighting and other branch circuits in 277 VAC systems.
