FAZ-D8/4 Eaton Miniature Circuit Breaker

The FAZ-D8/4 is a 4-pole, 8A D-curve supplementary miniature circuit breaker from Eaton/Moeller, intended for inductive loads with high inrush current, including motors, transformers and power supplies. Its thermal-magnetic trip system uses a 10–20x In magnetic threshold, while the trip-free mechanism supports operation within control panels, appliances and industrial systems. The device provides supplemental protection within equipment and is not designed to serve as a branch-circuit protector under NEC Article 240. It mounts on DIN rail and includes a contact position indicator. Measuring 17.7 mm per pole, the breaker is recognized to UL 1077 and certified to CSA C22.2 No.235, and it conforms to IEC 60947-2.
