Miniature circuit breakers from the FAZ series are available in 6 kA and 10 kA options. They come in single, double, and triple pole configurations with thermal and magnetic tripping mechanisms, designed for DIN rail mounting. The breakers feature three selectable tripping characteristics and breaking capacities of either 6 kA for low-cost applications or 10 kA for full rating.

They utilize a double-break contact system with an internal spark extinction chamber and a storing firing mechanism that allows for free tripping. The contact position is clearly indicated by a frontal switching lever, and they have a large terminal clamping capacity ranging from 0.75 to 16 mm².

These circuit breakers are compatible with DIN rails and conform to EN 50 022/DIN 46277-3. They meet design provisions B, C, and S according to the new international standard IEC 898, BS/EN 60-898.

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 and heating loads in households and smaller buildings. Curve C provides instantaneous tripping at currents 5 to 10 times the rated value, ideal for circuits with larger inrush currents, including industrial equipment, larger buildings, motors, and fluorescent lamps.

Curve S is designed for applications where undesirable tripping occurs with faster tripping. It has a short circuit response threshold from 13 to 17 times the rated current and an overload threshold from 1.05 to 1.3 times the rated current, making it ideally suited for protecting control circuits where very large inrush currents are expected, such as transformers.
