The Siemens 3RV1011-0EA15 is a SIRIUS motor-protective circuit breaker with a Class 10 trip characteristic, sized for 45 mm width on a 35 mm DIN rail (DIN EN 60715).
The 45 mm width and 75 mm depth fit standard motor-starter slots in a SIRIUS lineup.
Trip class and breaking capacity
Class 10 trip means it clears a stalled-rotor condition within 10 seconds at 7.2× setting — the standard for standard-duty motor starting. The 100 kA breaking capacity at 400 V (and at 690 V) gives you full selectivity with a 100 kA SCCR-rated upstream feeder breaker; no need to oversize the branch.
Environmental and auxiliary ratings
Rated for -20 to +60 °C operating ambient, with storage down to -50 °C. The auxiliary contact block switches 1 A at 24 V and 2 A at 120 V — enough for a PLC input or a contactor coil in the same panel.
