Square D FA26030AC Thermal Magnetic Circuit Breaker

FA26030AC is a 30A, 2-pole molded-case circuit breaker in Square D’s FA I-Line family, rated for 600V. It uses a thermal-magnetic trip mechanism to provide overload and short-circuit protection on 2-pole circuits in industrial and commercial power-distribution setups, with I-Line plug-in mounting and an FA frame construction for panel installations. Interrupting ratings are 25 kA at 240 VAC, 18 kA at 480 VAC, and 14 kA at 600 VAC, reflecting its performance across common voltage ranges. The unit’s approximate physical footprint is 4.13 inches tall by 6.4 inches long and about 3 inches wide. In Schneider Electric’s product lifecycle, FA26030AC was discontinued on December 8, 2020, with end-of-service on December 31, 2020; Schneider Electric lists the PowerPacT B line as a replacement option for similar 30 A, 2P, 600V applications (for example, 30A, 2P, 600Y/347VAC, 14kA, I-Line, thermal-magnetic). This FA model is typically used to protect feeders and branch circuits in switchgear and panelboards where compact, reliable 2-pole protection is required.
