Schneider Electric's FA36040 is a 40 A, 3-pole molded‑case circuit breaker designed for I‑Line panelboard installations, with a 600 V rating and an I‑Line plug‑in connection. It uses a thermal‑magnetic trip mechanism and provides an interrupting rating of 14 kA at 600 V, making it suitable for protecting feeders and branch circuits in commercial and light industrial distribution. Schneider Electric lists FA36040 as replaced by PowerPact B models in newer catalogs, such as the BDA36040, so verify compatibility with current panelboard models if you're replacing an existing FA36040 in an installation.
