Siemens 3RW50 Series Soft Starter, 132kW Power, 3 Phase - 3RW5073-6AB14

This soft starter reduces inrush and mechanical stress when starting three-phase motors in industrial installations. Designed for operation on 200 to 480 V supplies with integrated bypass switching and an analogue output, it supports communication modules such as PROFINET and Modbus and accepts screw mounting. The unit provides adjustable current limiting and soft stopping routines while maintaining performance at elevated ambient temperatures.

Features and Benefits:

• 250 A operational current ensuring high motor load capacity
• Adjustable current limit 130…700% for controlled start torque
• Start ramp adjustable 0…20 s to reduce mechanical shock
• Electronic motor overload protection for continuous monitoring
• 4…20 mA analogue output enabling process integration

Applications

• Used for centrifugal pump soft starting in plants
• Suitable for conveyor drive motor start control
• Ideal for compressors with high start current demands
• Can be used with PROFINET systems for energy management
• Used with long motor cables up to 800 m for remote motors

What control supply voltage does it require?

It operates from an AC control supply of 110…250 V at 50 to 60 Hz.

How does it cope with elevated ambient temperatures?

Rated to operate up to +60 °C with specified derating above 40 °C.

What protection and safety standards does it meet?

It conforms to multiple approvals including CE, UL and CSA and meets IEC 60947-4-2 requirements.

What mounting and connection options are available?

The device is screw-mounted with busbar main connections and screw-type control terminals.

How is bypass implemented and what is its buffering time?

An integrated bypass contact system is provided with 100 MS buffering for both main and control circuits.
