3RW3026-1BB14, Soft Starter, 11 kW, 25 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: 3RW3026-1BB14

The Siemens 3RW3026-1BB14 is a SIRIUS 3RW30-series motor soft starter rated for 25 A (Ie at 40 °C) and specified for motors up to 11 kW at 400 V (5.5 kW at 230 V). It operates on a three-phase supply of 200–480 V AC (50/60 Hz) and accepts a control supply of 110–230 V AC/DC. Designed for compact control panels (S0 size), this model uses thyristor-based voltage control to limit inrush current and reduce mechanical stress during starts. Typical applications include pumps, fans, compressors and small conveyor drives where basic, reliable soft starting and reduced electrical/mechanical wear are required. Standout, verified features for this SKU include an integrated bypass contact to reduce power dissipation during run, IP20 finger-protected enclosure, and built-in motor overload protection—making the 3RW3026-1BB14 a straightforward choice for procurement teams seeking a compact, easy-to-install soft starter for standard industrial motor-starting needs.
