Siemens 3RV2011-1AA10 Motor Protector Starter

Siemens SIRIUS 3RV2 motor protector starter, model 3RV2011-1AA10, is a compact three-pole S00 circuit-breaker style device designed for motor protection in control panels. It combines thermal overload protection with a dedicated release: an A-release adjustable from 1.1 to 1.6 A and an N-release rated at 21 A, all in a screw-terminal package for straightforward wiring. Rated for up to 690 V AC and engineered for Class 10 trip performance, this motor protector is intended to safeguard small three-phase motors in starter circuits used with contactors. As part of the SIRIUS 3RV2 family, it offers a standard mounting footprint suitable for panel installation and easy integration into Siemens’ motor protection ecosystem. Three-pole design provides protection across all phases with robust, screw-terminal termination for reliable connections in industrial environments. Typical applications include pumps, fans, conveyors, and other machine loads where reliable, compact motor protection is required in a minimal-space enclosure. As a member of the 3RV2 family, the 3RV2011-1AA10 shares the S00 frame and compatible terminal style with other motor protection devices, simplifying control panel layout and maintenance in industrial automation.
