Siemens 3RW52 22 kW, 480V AC, 3 Phase Screw Fixing IP00 Soft Starter 3RW5216-1AC04

Siemens 3RW5216-1AC04 Soft Starter is designed for efficient and reliable soft starting and stopping of three-phase asynchronous motors up to 22 kW power rating at 480V AC supply voltage. Its screw fixing mount and IP00 protection rating make it suitable for various electrical automation, industrial manufacturing, and HVAC applications requiring gentle motor startups and load management.

This device significantly reduces current peaks and mechanical stress on motors during startup, preventing supply voltage fluctuations and extending equipment life. The integrated bypass circuit enables a compact construction that saves valuable control cabinet space and reduces heat dissipation, thus improving energy efficiency.

Siemens has incorporated intelligent monitoring functions to protect the soft starter from overheating and to safeguard motors against overload conditions, enhancing operational safety and reliability. Users can limit the startup current to user-defined maximum values, ensuring tailored control over motor behavior.

The three-phase control system is especially beneficial for high power motors and inside-delta circuit configurations. Additionally, the innovative Soft Torque function ensures smooth motor acceleration for sensitive applications. The device supports remote reset capabilities to quickly clear faults, minimizing downtime.

Parameter settings are user-friendly with rotary potentiometers enabling straightforward commissioning. Optional plug-in communication modules facilitate integration into industrial networks using protocols such as PROFINET, PROFIBUS, and Modbus TCP. Various Human Machine Interface (HMI) modules can be installed either on the device or the control cabinet door for convenient operation and monitoring.
