The Siemens SIRIUS 3RV1011-0BA10-ZW97 is a motor-protective circuit breaker designed for motor protection, with a Class 10 trip characteristic and a 100 kA breaking capacity at 400 V AC. It mounts via screw and snap-on onto 35 mm DIN rail per DIN EN 60715, fitting standard panel layouts.
What the ratings mean for your panel
The 100 kA breaking capacity at 400 V AC means this breaker can safely interrupt fault currents up to that level without upstream devices needing to clear the fault — critical for high-fault panels near large transformers. The Class 10 trip clears overloads within 10 seconds at 7.2× rated current, matching standard motor start profiles for pumps and conveyors. Phase failure detection is built in, so a lost phase on the line side trips the breaker rather than letting the motor single-phase and burn.
Mounting and integration
Screw and snap-on mounting onto 35 mm DIN rail per DIN EN 60715. Mounting position any. Clearance: 20 mm upwards, 20 mm downwards, 9 mm at the side. Forwards and backwards zero clearance. Screw-type terminals for the main current circuit; terminal capacity 2x (0.5...1.5 mm²) or 2x (0.75...2.5 mm²) solid or stranded. Main contact screw size M3.
