Siemens 3RV2011-1AK10 motor protection circuit breaker, size S00, is a compact three‑pole device from the Sirius 3RV2 family that provides both overload and short‑circuit protection for small to mid‑size motors in control panels. It combines a thermal overload element (Class 10) with a magnetic release and is rated for 400 V AC mains (50/60 Hz), with a nominal current setting of 9 to 12 A, making it suitable for motors up to about 5.5 kW at 400 V. The unit is designed for DIN rail mounting and uses screw terminals for secure connections and easy wiring; its standard switching capacity aligns with the motor‑protection purpose of the 3RV2 family. In Siemens catalogs it is listed as 3RV2011-1KA10 within the same family, confirming the core specifications and intended applications for motor protection in pumps, fans, conveyors, and other automation panels.
