Product details

SIRIUS soft starter for motor starting duty

The Siemens 3RW5224-1AC04 is a SIRIUS-brand hybrid soft starter designed to ramp motors up and down smoothly, reducing inrush current and mechanical stress on pumps, conveyors, and fans. It covers a rated voltage range of 200 to 480 V and sets a minimum starting current of 20 A, with a trip class of CLASS 10A (default), 10E, or 20E per IEC 60947-4-2 — meaning it handles standard and heavy starting duty without nuisance tripping on longer acceleration times.

Fieldbus and control connectivity

This soft starter comes equipped for modern control networks: PROFIBUS, Modbus RTU, Modbus TCP, EtherNet/IP, and PROFINET are all on board, plus PROFIenergy for energy management when used with the PROFINET communication module. Analog output is configurable as 4-20 mA (default) or 0-10 V via the High Feature HMI. Auto-reset and remote reset (by cycling the 24 V control supply) are standard, so a line-down restart can be handled without a panel visit.

Mounting and environmental limits

The unit is screw-fixed (not DIN-rail snap-on) and measures 306 mm high by 185 mm wide by 203 mm deep. Clearance requirements: 100 mm above, 75 mm below, 10 mm forward, 0 mm backward, 5 mm at the sides. Pollution degree 3 per IEC 60947-4-2 means it's rated for industrial environments with conductive dust or moisture.

Frequently asked questions

What is 3RW5224-1AC04's listed depth (203 mm) on this Soft Starters line?

The depth is 203 mm, with width 185 mm and height 306 mm. Mounting is screw-fixed with specified clearances: 100 mm above, 75 mm below, 10 mm forward, 0 mm backward, 5 mm at the sides.
