Rated at 0.63 A continuous current, it protects small motor loads up to 0.18 kW at 400 V AC, with a massive 100 kA breaking capacity at 400 V — that SCCR headroom means it clears high fault currents without upstream coordination headaches.
Terminals accept solid or stranded wire: 2x 1–2.5 mm² and 2x 2.5–6 mm² per clamp, or AWG 14–10 for the main contacts. That dual-range grip handles both control wiring and power tails without piggyback lugs. Dimensions: 45 mm wide, 97 mm tall, 96 mm deep — standard 3-module footprint on the rail.
The 100 kA breaking capacity at 400 V is the same across 240 V, 500 V, and 690 V — full-range performance, no derating at higher voltages. That's unusual for a compact breaker and simplifies selectivity studies. Rated insulation voltage 690 V, surge withstand 6 kV. The 5.5 W power dissipation at rated current (1.8 W per pole) is low enough that you can pack these side-by-side without thermal derating in most enclosures. No ground fault or phase failure detection built in — this is a straightforward thermal-magnetic breaker for starter duty. If you need those functions, add an external relay or step up to the SIRIUS 3RV2 series with electronic trip. Operating frequency max 15 operations per hour at AC-3 — fine for occasional start/stop on a conveyor or pump, not for high-cycling applications like a stamping press.
