3RW5213-1AC14, Soft Starter, 5.5 kW, 13 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: 3RW5213-1AC14

The Siemens 3RW5213-1AC14 is a SIRIUS 3RW52 digital soft starter rated for 13 A and specified for motor applications up to 5.5 kW (at 400 V). It is designed for three-phase mains with a wide supply-voltage range of 200–480 V AC and uses a 110–250 V AC control supply. Typical motor compatibility for this SKU includes small to medium three-phase asynchronous motors used in pumps, conveyors and similar industrial drives where a 5.5 kW continuous motor at 400 V is required (inline and inside-delta connection options affect the exact kW rating at other mains voltages). This unit includes an internal bypass and integrated motor overload protection, simplifying wiring and improving efficiency during run conditions. The starter is provided with screw terminals and an analog output option on the product configuration, making it suitable for systems that need simple process feedback or integration into basic control panels. With an IP20 enclosure rating and a compact form factor, the 3RW5213-1AC14 is intended for panel mounting in industrial control cabinets where controlled starts, reduced mechanical stress and motor protection are needed.
