Schneider Electric SE FAB-32020 Circuit Breaker

FAB32020 Square D by Schneider Electric is a three-pole molded-case circuit breaker rated for 20 A, designed for 240 VAC operation and 250 VDC, and it belongs to Schneider's PowerPact B family with thermal-magnetic trip protection for reliable overcurrent safeguarding in electrical panels. It features a line-side I-Line connection and ABC phase connections with load-side lugs that accept 14-4 AWG aluminum or copper conductors, and it is rated at 80% of its nominal rating for typical panel environments. The device is specified for 240 VAC and 250 VDC, with data sheets noting its place in the PowerPact B family and documenting higher-voltage interrupting ratings (e.g., up to 18 kA at 480Y/277 VAC on certain configurations), making it suitable for branch-circuit protection in commercial panels.
