3RW3013-1BB14, Soft Starter, 1.5 kW, 3.6 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: 3RW3013-1BB14

The Siemens 3RW3013-1BB14 is a SIRIUS S00-class soft starter designed for compact, entry-level motor soft starting in industrial installations. Verified manufacturer data lists a rated motor capacity of 1.5 kW at 400 V (also 0.75 kW at 230 V) and a rated operational current of 3.6 A (at 40 °C). The device accepts a wide supply voltage range of 200–480 V AC and uses a separate control/auxiliary voltage of 110–230 V AC/DC for coil/control inputs. Ramp-up/start time is adjustable (0–20 s), allowing controlled voltage ramping to reduce mechanical stress and limit starting current. Its small S00 frame size and compact dimensions make it suitable where panel space is limited.

Typical applications include small pumps, fans and conveyors, light compressors and other machines driven by three-phase asynchronous motors up to the verified power ratings above. The starter is intended for basic soft starting duty rather than advanced motor management; it provides simple, repeatable soft starts with reduced mechanical wear and smoother line behaviour compared with direct-on-line starting. Standout practical features for this SKU (manufacturer-specified) include screw terminal connections, compact S00 housing for space-saving mounting, and integrated jumper/contact arrangement for bypassing after start.

Who should consider this model: procurement or maintenance teams looking for a low-footprint, cost-effective motor soft starter for small three-phase motors where straightforward soft-start functionality, a broad supply-voltage capability (200–480 V AC), and simple installation are primary requirements.
