The adjustable overload range is 9...12.5 A, and the instantaneous magnetic trip fires at 163 A — meaning it clears a bolted fault fast enough to protect the contactor and cable, not just the motor. Rated operational voltage covers 20...690 V. The interrupting capacity is 100 kA at 240 V and 400 V AC, dropping to 42 kA at 500 V and 6 kA at 690 V AC. ## Termination and panel fit Spring-type terminals on the main circuit and auxiliary contacts — no screwdriver needed for the power wiring, which speeds up panel assembly. The S00 footprint (45 mm wide, 97 mm deep) snaps onto 35 mm DIN rail per DIN EN 60715. ## What CLASS 10 means for motor starting That's the standard for standard-duty induction motors — pumps, fans, conveyors that accelerate to full speed in a few seconds. It won't nuisance-trip on a normal start, but it clears quickly if the rotor locks. For high-inertia loads (centrifuges, flywheels) you'd want CLASS 20 or 30; for submersible pumps or hermetic compressors, CLASS 10 is the right call.","metaTitle":"Siemens 3RV2011-1KA25-ZX95 SIRIUS Motor Circuit Breaker, 12.","metaDescription":"Siemens SIRIUS 3RV2011-1KA25-ZX95 motor protection circuit breaker, 12.5 A, CLASS 10, 100 kA at 400 V, spring terminals, active production.
