The Siemens SIRIUS 3RV1011-1JA15 is a motor-protective circuit breaker rated for CLASS 10 trip — meaning it disconnects within 10 seconds at 7.2× the thermal setting, which is the standard for standard-duty induction motors (pumps, fans, compressors) that don't need the faster CLASS 5 or the slower CLASS 20.
At 400 V it drops to 13 kA, at 500 V to 3 kA, and at 690 V to 2 kA. The evidence also lists required backup fuse ratings (gL/gG) at each voltage level: 80 A at 240 V, 63 A at 400 V, 50 A at 500 V and 690 V. If you're coordinating with upstream fuses, those are the numbers to use.
Motor current and auxiliary contacts
For motor loads, the breaker carries 1.5 hp at 230 V, and 10 A at both 480 V and 600 V — that maps to a small motor, roughly 5–7.5 hp depending on voltage. The auxiliary contact block is rated 1 A at 24 V, 2 A at 110–125 V, 0.5 A at 230 V, and 0.15 A at 60 V. Those are the switching ratings for the signal side, not the main power path.
Environmental and wiring
The terminals accept solid or stranded wire: 2× (0.5 to 1.5 mm²) or 2× (0.75 to 2.5 mm²).
