Schneider Electric FAB36040 I-Line Circuit Breaker

Schneider Electric FAB36040 I-Line molded-case circuit breaker delivers 40 A of protection in a 3-pole package built for I-Line panelboards and 600 V systems. Part of the FA/I-Line family, this bolt-on mounting device uses a thermal-magnetic trip to protect three-phase feeders and branch circuits in commercial and light-industrial installations. It is UL, CSA, and NOM listed, reflecting standard North American electrical-code compliance, and its compact, robust construction is designed for seamless integration within Schneider Electric’s I-Line ecosystem. The FAB36040’s three-pole design and 600 V rating make it a straightforward direct-replacement option for compatible FA/I-Line breakers, helping maintain consistent protection across an I-Line panelboard while supporting reliable operation in typical 60 Hz power environments.
