The Siemens SIRIUS 3RV1011-0DA10-ZI41 is a motor protection circuit breaker sized for a 0.09 kW motor at 400 V AC, with a continuous current rating of 0.32 A and a CLASS 10 trip characteristic — meaning it will trip within 10 seconds at 7.2x the thermal setting, which is the standard for protecting standard induction motors during startup without nuisance tripping on normal acceleration. Rated for 690 V AC and delivering a 100 kA breaking capacity across the full voltage range (240 V through 690 V), this breaker can handle high fault currents common in industrial distribution without needing upstream fuses for short-circuit protection — it's self-protecting at those levels. No ground-fault detection here — that's handled separately if needed.
The 45 mm width and 81 mm depth are standard for the SIRUS 3RV1 frame — leaves room for adjacent contactors or overloads in a motor starter lineup. Screw-type terminals on the main circuit accept 2x (0.5...1.5 mm²) solid or stranded, or 2x (0.75...2.5 mm²) — fine for the 0.32 A motor branch. AWG equivalent is 2x (18...14). No auxiliary contacts included (0 built-in), so if you need remote status, add the separate auxiliary switch block.
Shock-rated to 25g for 11 ms — survives typical panel vibration and transport. Rated for installation up to 2,000 m altitude without derating. Mechanical endurance is 100,000 operations on the main contacts.
