SIRIUS soft starter 200-480 V 171 A-3RW5236-6AC14

Product Description

SIRIUS Soft Starter 200–480 V 171 A – 3RW5236-6AC14

The Siemens 3RW5236-6AC14 is a high-performance SIRIUS 3RW52 series soft starter, designed for smooth and controlled starting and stopping of three-phase induction motors. It reduces inrush current, mechanical stress, and voltage dips, ensuring improved motor protection, stable network performance, and longer equipment life in industrial applications.

With a rated operational current of 171 A and a supply range of 200–480 V AC, this soft starter is suitable for heavy-duty motor applications such as large pumps, compressors, conveyors, crushers, mixers, and HVAC systems.

It uses three-phase controlled thyristor technology with an integrated bypass system, which ensures efficient operation after startup by reducing heat loss and improving energy efficiency. Advanced features like adjustable ramp settings, current limiting, motor protection, and diagnostics make it ideal for modern automation and process industries.
