SIRIUS soft starter 200-480 V 47 A-3RW5524-1HA14

Product Description

SIRIUS Soft Starter 200–480 V 47 A – 3RW5524-1HA14

The Siemens 3RW5524-1HA14 is a high-performance SIRIUS 3RW55 series soft starter, designed for smooth starting and stopping of three-phase induction motors. It reduces inrush current, mechanical stress, and voltage dips, ensuring stable motor operation and improving overall electrical system reliability.

This model operates in a 200–480 V AC voltage range with a rated operational current of 47 A, making it suitable for medium-duty industrial motor applications such as pumps, compressors, conveyors, mixers, and HVAC systems.

It uses thyristor-based phase control with integrated bypass contacts, which minimizes heat dissipation after motor start and improves energy efficiency. The device also supports adjustable ramp-up/ramp-down, current limiting, motor overload protection, thermistor input, and advanced diagnostics, making it suitable for modern automation and process control systems.

According to Siemens datasheet information, this model is part of the 3RW55 high-performance soft starter family, with typical motor power capability of around 22 kW at 400 V (standard line connection), depending on application and configuration.
