Siemens 3RV2011-1AA15 Motor Starter Protector

Siemens 3RV2011-1AA15 is a SIRIUS 3RV2 motor starter protector (S00 size) delivering reliable motor protection with a compact footprint. This three‑pole device provides a 21 A nominal current rating for motor protection and includes a transverse auxiliary contact (1 NO + 1 NC) wired via screw terminals for straightforward control wiring. Rated for up to 690 VAC, it uses thermal-magnetic protection (Class 10) to guard motors against overload and to enable safe disconnects in fault conditions. Designed for small‑to‑mid‑size motors in machines, conveyors, and other panel‑mounted applications, the 3RV2011-1AA15 integrates protection and signaling in one compact unit, reducing panel complexity while maintaining standard switching capacity.
