The Siemens 3RV2011-1DA10-0BA0 is a SIRIUS motor-protection circuit breaker sized S00, built for protecting three-phase induction motors up to 690 V. It carries a CLASS 10 trip curve, meaning it will open within 10 seconds at 7.2× the thermal setting — fast enough to keep a locked-rotor condition from cooking the windings on a typical pump or conveyor motor. Breaking capacity is 100 kA at 400 V AC and 500 V AC, dropping to 10 kA at 690 V AC. That 100 kA figure means this breaker can interrupt a fault current up to that level without the arc re-striking — a real advantage when you're coordinating downstream of a large transformer or in a plant with high available fault current. It detects phase failure and mounts on a 35 mm DIN rail per DIN EN 60715, with screw terminals for the main circuit. The enclosure dimensions are 45 mm wide, 97 mm deep, and 97 mm tall — a standard S00 footprint that fits the same panel cutout as other SIRIUS S00 gear.
Mounting and integration
Snaps onto a 35 mm DIN rail with the screw-and-snap mechanism — no tools for the rail, just a screwdriver for the terminals. The screw terminals accept 2×(0.75…2.5 mm²) solid or stranded, or 2×4 mm², with a Pozidriv size 2 tip. Mounting position is any; clearance above and below is 50 mm, sides 30 mm, zero forward or backward clearance needed. The S00 size is the smallest frame in the SIRIUS 3RV2 family, so it saves panel space compared to the S0 or S2 frames. If you're kitting a control panel with multiple motor starters, this breaker shares the same DIN-rail footprint as the matching SIRIUS contactors.
