Siemens 3RV1011-1DA10 Manual Motor Starter

Siemens 3RV1011-1DA10 is a size S00 manual motor starter from the SIRIUS 3RV1 family, designed for motor protection in DIN-rail panels. It combines switching with protective functions, featuring an adjustable overload release settable 2.2 to 3.2 A (A-rel) and a fixed short-circuit release rated at 42 A, with a voltage rating up to 690 V AC. The device uses screw terminals for connections and includes a manual reset button for reinitialization after tripping; optional front- and side-mounted auxiliaries can be added for signaling or control interlocks. As a Class 10 motor protection circuit breaker, it serves to protect small motors in electrical control panels and machine assemblies that require a compact S00 form factor and DIN-rail mounting. It is part of Siemens' motor protection lineup under the 3RV1 family and accepts standard control wiring compatible with common industrial automation installations. This unit provides a dedicated overload and short-circuit protection directly at the motor’s supply line, simplifying panel wiring and maintenance within its 2.2–3.2 A operating window.
