SIRIUS soft starter 200-480 V 38 A-3RW5217-1AC14

Product Description

SIRIUS Soft Starter 200–480 V 38 A – 3RW5217-1AC14

The Siemens 3RW5217-1AC14 is a robust and efficient SIRIUS soft starter from the 3RW52 series, designed for smooth starting and stopping of three-phase induction motors. It reduces starting current peaks, mechanical stress, and voltage dips, ensuring improved motor life and stable electrical network performance in industrial applications.

Operating in a 200–480 V AC supply range, this soft starter supports a rated operational current of 38 A, making it suitable for medium-duty motor applications such as pumps, fans, compressors, conveyors, mixers, and HVAC systems.

The device uses three-phase controlled switching with integrated bypass contacts, which ensures high efficiency after startup by reducing heat dissipation and energy losses. It also includes adjustable ramp-up/ramp-down settings, current limiting, motor protection functions, and diagnostic features, making it a reliable solution for modern automation systems.
