Siemens 3RV1031-4FA10 Manual Motor Starter

Siemens 3RV1031-4FA10 is a three-pole motor protection circuit breaker that functions as a manual motor starter within the Sirius 3RV1 family, delivering integrated overload protection for small to mid-size motors. It provides adjustable overload protection in the 28–40 A range, allowing precise matching to the motor’s full-load current, and is rated up to 690 V AC with a short-circuit interrupt capacity of up to 4 kA. This thermal/magnetic trip device features Class 10 protection and is designed for DIN-rail mounting in control panels, making it a compact solution for motor feeders in pumps, fans, conveyors, and other general industrial equipment where reliable motor protection is required. As a 3-pole unit, it integrates protection and switching within a small footprint and is intended to work alongside other Siemens Sirius protection components for cohesive panel assemblies.
