Schneider Electric FAB-26020-AC Circuit Breaker

Schneider Electric's Square D FAB26020AC Molded Case Circuit Breaker is a 600-volt, 20-amp, two-pole, single-phase protective device designed for I-Line plug-in installations in industrial and commercial panels. As part of the FA/FAB family, it provides thermal-magnetic overcurrent protection for distribution circuits and uses I-Line drawout connectors compatible with Schneider Electric's I-Line panel systems. The FA26020AC/FAB26020AC series lists an 18 kA interrupting rating at 480 V, a rating commonly associated with 600 V class MCCB applications to ensure robust interruption for typical industrial setups. Schneider Electric notes FAB26020AC as discontinued with end-of-life in 2020 and recommends modern PowerPacT B 20A, 2-pole devices as contemporary replacements within the same protection framework for new installations or repairs. This Square D device carries the familiar branding and is documented in catalog references as a two-pole, 20-amp, 600 V MCCB compatible with I-Line mounting, suited for use in panels and switchgear that rely on 600 V circuits.
