3RW5224-1AC14, Soft Starter, 22 kW, 47 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: 3RW5224-1AC14

The Siemens 3RW5224-1AC14 is a SIRIUS 3RW52 soft starter designed for three-phase industrial motors supplied from 200–480 V AC. This SKU is rated for a nominal operational current of 47 A and is specified for a motor power of 22 kW at 400 V (40 °C), making it suitable for mid‑sized motors used in pumps, fans, conveyors and other continuous‑duty driven equipment. The unit accepts a control/supply voltage for the control circuit of 110–250 V AC, uses screw‑type terminals, and includes an integrated bypass to reduce energy dissipation and cabinet heating after start-up. Verified product functionality includes motor overload protection/thermal monitoring and an analog output option for process monitoring. Modular communication options (PROFINET/PROFIBUS/Modbus TCP) are available via plug‑in modules, allowing integration into industrial control networks when required. In practice, this model is chosen where a reliable, compact soft starter is needed to limit inrush current, reduce mechanical stress during starts, and provide basic motor protection with the option to add networked monitoring.
