Siemens 3RV1011-1AA15 is a SIRIUS-branded circuit breaker for motor protection, rated for 20... 690 V and carrying a Class 10 trip characteristic. Breaking capacity sits at 100 kA at 400 V and 500 V, dropping to 2 kA at 690 V — the high 400 V figure means it handles bolted faults on a strong industrial grid without cascading upstream.
Auxiliary contact ratings and wiring
The integrated auxiliary contact switches 1 A at 24 V, 2 A at 110–125 V, and 0.5 A at 230 V — enough for PLC input or contactor coil feedback in a 24 VDC control loop. Terminals accept 2× (0.5... 1.5 mm²) or 2× (0.75... 2.5 mm²) solid or stranded wire, secured with M3 screws. The 9 mm side clearance and 20 mm upward/downward clearance simplify wiring in a dense row.
