Miniature circuit breakers, FAZ series, available in 6 kA and 10 kA. They come in single, double, and triple pole configurations, with thermally and magnetically tripping features for automatic operation. Designed for DIN rail mounting, these breakers offer three selectable tripping characteristics and breaking capacities of either 6 kA for low-cost applications or 10 kA for full rating.

They feature a double-break contact system with an internal spark extinction chamber and a storing firing mechanism with free tripping. A clear indication of contact position is provided by a frontal switching lever, and they have a large terminal clamping capacity ranging from 0.75 to 16 mm².

These breakers are compatible with DIN rails and conform to EN50 022/DIN 46277-3, as well as the design provisions B, C, and S according to the new international standard IEC 898, BS/EN60-898.

Curve B ensures comfortable tripping at currents 3 to 5 times the rated value, suitable for circuits with moderate inrush currents, such as incandescent lamps, heating loads, and household applications. Curve C allows instantaneous tripping at currents 5 to 10 times the rated value, ideal for circuits with larger inrush currents, such as industrial equipment, larger buildings, motors, and fluorescent lamps.

Curve S is designed for applications where undesirable tripping may occur with faster tripping. The short circuit response threshold ranges from 13 to 17 times the rated current, while the overload threshold ranges from 1.05 to 1.3 times the rated current. These breakers are ideally suited for protecting control circuits where very large inrush currents are expected, such as transformers.
