3RW5513-1HA14, Soft Starter, 5.5 kW, 13 A, 200 to 480V AC

Siemens 3RW55 Soft Starter Series – Overview

Siemens 3RW55 soft starters are heavy-duty motor starting solutions designed for high-power industrial applications requiring robust and reliable control of three-phase asynchronous motors. The 3RW55 series focuses on reducing mechanical stress, limiting inrush current, and supporting very high motor power ratings with advanced motor protection and monitoring capabilities. With a rugged design and suitability for demanding operating conditions, Siemens 3RW55 soft starters are well suited for large pumps, compressors, crushers, conveyors, mills, and other heavy industrial machinery where dependable motor starting and long-term reliability are critical.

Product Description: 3RW5513-1HA14

The Siemens 3RW5513-1HA14 is a SIRIUS 3RW55 soft starter rated for a nominal operational current of 13 A and intended for supply voltages from 200 to 480 V AC. At 400 V the unit is specified for motor power up to 5.5 kW (the device’s product data also lists lower-rated power at 230 V). Control supply for the starter is 110–250 V AC. Typical motor compatibility includes small-to-medium three-phase asynchronous motors in the ~3–5.5 kW class (depending on system voltage and connection), making this SKU suitable for feeders driving pumps, small compressors, conveyors and fan loads where limiting inrush and reducing mechanical stress are required. Verified design details for this model include screw-terminal main connections, electronic motor overload protection, and an IP20 enclosure rating, supporting panel or control-cabinet installation in industrial environments. This configuration is aimed at engineers and procurement teams who need a compact, manufacturer-supported soft starter for reliable industrial motor starting and basic motor protection in 200–480 V networks.
