Siemens 3RW5215-1AC04 (SIRIUS 3RW soft starters): SIRIUS soft starter 200-480 V 25 A, 24 V AC/DC Screw terminals Analog output.
SIRIUS 3RW soft starters ramp the motor voltage up and down so that pumps, fans, compressors and conveyors start without the current peak and mechanical shock of a direct-on-line start.

Compatibility and replacement
Compare the rated current, motor power, control supply voltage and connection type (screw or spring-loaded) with the old soft starter; the Siemens data sheet above gives the exact values.
Replacement checklist
- Compare the full order number 3RW5215-1AC04 with the label on the old unit, including the last digits (they identify the version).
- Check the supply voltage and wiring of the old unit before installing the new one.
- Look for signs of overvoltage, water or heat damage in the cabinet so the new part does not fail for the same reason.
Frequently asked questions
Does it need an overload relay?
That depends on the model: check the protective functions listed in the Siemens data sheet, and add a 3RU2 overload relay or 3RV2 breaker where motor protection is not integrated.
Can it reduce the starting current?
Yes. Soft starters limit the inrush current by ramping the voltage; the achievable reduction depends on the load and the settings.
Can you help me identify the right replacement?
Yes. Send us a photo of the label of the old part, or its full order number, and we will confirm the exact match or the official successor before quoting.
Can I get a datasheet?
The official manufacturer datasheet is the source of the technical data above; we can send the PDF with the quotation on request.
Do you ship to my country, and what is the warranty?
Yes. RendatSP ships worldwide from Yiwu, China, by air in 5 to 7 days once the part is ready, and every part carries a 1-year warranty. Send the order number and quantity on WhatsApp and we will reply with a quotation.
