FAZ-S4/2 Eaton Miniature Circuit Breaker

The FAZ-S4/2 from Eaton/Moeller is a supplementary miniature circuit breaker rated at 4A with a 2-pole configuration and an S-curve trip characteristic. Its 13–17× In instantaneous trip response is suited to inductive loads that experience high inrush currents, helping avoid nuisance tripping. The breaker is intended for control circuits, motors, transformers, and power supplies. Thermal-magnetic overcurrent protection combines with current limiting for rapid interruption of short circuits. It mounts on DIN rail and occupies a compact 17.7 mm module width per pole. UL 1077 recognition, CSA certification, IEC 60947-2 compliance, and CE marking for international use.
