FAZ-C20/1-RT-SP Eaton Miniature Circuit Breaker

The FAZ-C20/1-RT-SP is a single-pole miniature circuit breaker from Eaton/Moeller designed for branch-circuit protection in industrial and commercial applications. It carries a 20A rating with a C-curve trip characteristic, while thermal-magnetic overcurrent protection addresses excessive current and elevated temperature conditions. The breaker is UL 489 and CSA certified, with a 10 kAIC rating under UL/CSA and capability up to 14 kAIC under IEC. Ring-tongue terminals provide secure connections, and a trip-free mechanism is incorporated for operation within its specified protection function. Typical applications include motor control, PLCs, power supplies, and HVAC systems. The obsolete Eaton part number is WMZT1C20T.
