3RW5216-1AC14, Soft Starter, 15 kW, 32 A, 200 to 480V AC

Siemens 3RW52 Soft Starter Series – Overview

Siemens 3RW52 soft starters are high-performance motor starting solutions designed for demanding industrial applications requiring precise and reliable control of three-phase asynchronous motors. The 3RW52 series focuses on reducing mechanical stress, limiting inrush current, and supporting higher motor power ratings with advanced protection functions compared to compact soft starters. With robust construction and enhanced motor protection capabilities, Siemens 3RW52 soft starters are well suited for heavy-duty applications such as large pumps, compressors, conveyors, mixers, and industrial process machinery where dependable motor starting and operational reliability are critical.

Product Description: 3RW5216-1AC14

The Siemens 3RW5216-1AC14 is a SIRIUS 3RW52 motor soft starter specified for three-phase supply voltages from 200 to 480 V AC. This SKU is rated for a nominal operational current of 32 A and is specified for motor power up to 15 kW (rated at 400 V), making it suitable for medium‑power industrial motors such as larger pumps, fans, small compressors and conveyors. The unit uses screw terminal connections and accepts a control/auxiliary supply of 110–250 V AC; it also provides an analog output for integration into basic control and monitoring schemes. Designed for industrial motor starting where reduced mechanical stress and limited inrush current are required, the 3RW5216-1AC14 is a practical choice for engineers and procurement teams specifying a compact, serviceable soft starter for standard three‑phase machines in process, water treatment, HVAC and material‑handling applications.
