Siemens SIRIUS 3RV2011-0CA10-ZX95 is a motor protection circuit breaker in Size S00, Trip Class 10, designed for screw and snap-on mounting onto 35 mm standard DIN rail per DIN EN 60715. It carries 100 kA breaking capacity at 400 V AC and includes phase failure detection but no ground fault detection. The unit is rated for any mounting position and operates from -20 to +60 °C.
Key Ratings & What They Mean
Rated voltage spans 20 to 690 V, covering most low-voltage motor circuits. The 100 kA breaking capacity at 400 V and at 690 V means it safely interrupts fault currents up to that level without upstream cascading — a strong SCCR for industrial panels. Trip Class 10 means the breaker trips within 10 seconds at 7.2× the thermal setting, standard for standard-duty motor starting. The AC-3 maximum switching rate of 15 cycles per hour limits how often you can cycle a motor under load — fine for pumps and conveyors, not for rapid jogging.
Mounting & Integration
Mounts via screw and snap-on onto 35 mm DIN rail per DIN EN 60715. Dimensions: 45 mm wide, 97 mm deep, 97 mm high. Clearance: 50 mm above and below, 30 mm at the sides, zero forward/backward. Accepts 2×(0.75 to 2.5 mm²) or 2×4 mm² solid/stranded wire with M3 screw terminals.
