3RW3016-1BB14, Soft Starter, 4 kW, 9 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: 3RW3016-1BB14

The Siemens 3RW3016-1BB14 is a compact SIRIUS 3RW30 motor soft starter rated for 9 A nominal current and a motor power rating of 4 kW (reference rating at 400 V). It is designed for three-phase supply voltages from 200 to 480 V AC, with a control supply of 110–230 V AC/DC, making it suitable for small to medium three‑phase asynchronous motors used in pumps, fans, light conveyors and compressors. The unit uses variable phase control to ramp motor voltage smoothly from a selectable starting voltage up to mains voltage, reducing mechanical stress and limiting start-up current. Its S00 size and IP20 enclosure make it a space-efficient choice for control panels where simple, reliable industrial motor starting is required. This model is appropriate for procurement teams and engineers specifying a straightforward soft starter for common industrial motor starting tasks where advanced communication or extended protection functions are not required.
