Miniature circuit breakers, FAZ series, 6 kA and 10 kA. Available in single, double, and triple pole configurations with thermal and magnetic tripping. Designed for DIN rail mounting, these breakers come with three selectable tripping characteristics. The breaking capacity can be chosen according to the characteristic: 6 kA for the low-cost series 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. There is a clear indication of contact position via a frontal switching lever, and they offer a large terminal clamping capacity from 0.75 to 16 mm².

These circuit breakers are compatible with DIN rails and conform to EN 50 022/DIN 46277-3, meeting 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, heating loads, 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, such as industrial equipment, larger buildings, motors, and fluorescent lamps. Curve S is designed for applications where undesirable tripping occurs with faster tripping, with 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 them ideally suited for the protection of control circuits where very large inrush currents are expected, such as transformers.
