Siemens 3RW5216-1TC14 480V AC, 22 kW, 3 Phase Soft Starter 3RW52 Series

Siemens 3RW5216-1TC14 3RW52 Series Soft Starter is engineered for the efficient soft starting and stopping of three-phase asynchronous motors operating at a maximum supply voltage of 480V AC with a power rating of 22 kW. Designed for industrial use, it drastically reduces the mechanical and electrical stress on motors by limiting current peaks during start-up, resulting in reduced wear and extended motor life.

This compact soft starter features an integrated bypass that lowers heat dissipation in control cabinets, boosting energy efficiency and saving valuable installation space compared to traditional star-delta starters and frequency converters. The device supports three-phase control, making it especially suitable for high output motors and inside-delta circuit installations.

With intelligent motor and device monitoring, the soft starter protects against overload and overheating conditions, enhancing operational reliability. The innovative Soft Torque function guarantees gentle motor starts to prevent mechanical shocks. Remote reset capabilities allow rapid fault clearance from distant locations, minimizing downtime.

Parameterization is simplified using rotary potentiometers, enabling quick and easy commissioning. The unit’s mounting type uses screw fixing and it carries an IP00 ingress protection rating, suitable for controlled industrial environments.

The 3RW52 Series Soft Starters are compatible with multiple communication protocols including PROFINET, PROFIBUS, EtherNet/IP, and Modbus TCP, allowing seamless integration into automation systems. The control supply voltage is flexible, accommodating 110-250 V AC supplies.

This model is manufactured in the Czech Republic, aligning with Siemens’ global quality standards, and is perfect for diverse industrial, manufacturing, and automation applications where motor management and energy savings are critical.
