Siemens AG 3RV2011-1CA10 Motor Protection Relay

The Siemens 3RV2011-1CA10 motor protection relay is a compact, DIN-rail mounted motor protection breaker in the S00 frame, designed for integration in control panels where space is at a premium and reliable motor protection is required. It combines thermal overload protection with a defined A-release setting of 1.8–2.5 A and a short-circuit release (N-release) of 33 A, supports operating voltages from 220 to 690 VAC, and is rated for motor power up to 0.75 kW. The device uses a screw-terminal connection and belongs to the Sirius 3RV2 family of motor protection devices, providing a robust, field-proven solution for low- and medium-voltage motor circuits where precise protection coordination matters. Typically deployed to guard small motors in industrial panels, this model delivers predictable tripping behavior based on defined current thresholds, enabling straightforward integration with existing protection schemes and simple maintenance in routine motor control applications.
