It's built for a 0.2 kW motor at 230 V AC, and it carries a 100 kA short-circuit breaking capacity at 240 V, 400 V, 500 V, and 690 V — that's high enough to sit upstream of most common distribution faults without needing a separate fuse or upstream breaker to back it up.
The 45 mm width means it takes up two standard 22.5 mm module spaces — a tight fit for a motor starter combo in a crowded enclosure. Clearance requirements: 50 mm above and below, 30 mm to the sides, and zero clearance forward or backward, so you can butt it against a backplane or adjacent devices. No ground-fault detection on this variant, so if you need that you'd look at a different order code in the same family.
