The 0.5 A rated current and 0.12 kW motor rating at 400 V size this breaker for small motor loads — fractional-horsepower pumps, fans, or conveyor drives. The 100 kA breaking capacity across all voltage points up to 690 V (–) is the same high-interrupt rating found on larger SIRIUS frames, so this compact 45 mm wide unit handles fault levels typical of main distribution panels, not just sub-feeds.
The 45 mm width and 81 mm depth fit standard enclosure backplanes with zero side clearance required. Spring-loaded terminals on both main and auxiliary circuits accept 0.25–2.5 mm² solid or 0.25–1.5 mm² finely stranded with ferrule — no screw torqueing, which speeds panel wiring. IP20 finger-safe touch protection on the front means the breaker can sit behind an open cabinet door during commissioning without shock hazard.
