3RW3017-1BB14, Soft Starter, 5.5 kW, 12.5 A, 200 to 480V AC

Siemens 3RW30 Soft Starter Series – Overview

Siemens 3RW30 soft starters are compact and cost-effective motor starting solutions designed for basic soft starting of three-phase asynchronous motors in standard industrial applications. The 3RW30 series focuses on reducing mechanical stress and limiting inrush current during motor start-up, providing a simple and reliable alternative to direct-on-line starting. With a straightforward design and easy commissioning, Siemens 3RW30 soft starters are well suited for pumps, fans, compressors, conveyors, and other simple motor-driven machines where basic motor starting control is sufficient.

Product Description: 3RW3017-1BB14

The Siemens 3RW3017-1BB14 is a SIRIUS 3RW30 series soft starter in size S00, specified for light industrial motor starting. It is rated for 12.5 A (at 40 °C) and is suitable for motors up to 5.5 kW at 400 V (3.0 kW at 230 V), with an operational supply-voltage range of 200–480 V AC. The unit accepts a control supply of 110–230 V AC/DC and is designed for ambient temperatures up to 40 °C without derating. Typical applications include single-direction starting of small pumps, fans, compressors and conveyor drives where limiting inrush current and reducing mechanical stress are primary requirements. Verified product details include IP20 enclosure (open-panel mounting), screw-terminal connections and the absence of integrated motor overload protection on the starter itself, so a separate motor protection relay or thermal overload must be used when required. The 3RW3017-1BB14 is a compact, economical choice when basic soft starting and a wide supply-voltage tolerance are needed.
