Siemens 3RVV3036-1AB05 Soft Starter

Siemens 3RW3036-1AB05 SIRIUS soft starter is an open‑type motor starting solution in size S2 that soft‑starts three‑phase motors up to 30 kW on 460–575 V AC networks, offering a continuous current rating of 45 A. It uses a 24 V AC/DC control supply and screw‑terminal connections for straightforward integration into standard control panels, with an ambient operating temperature up to 40°C. As part of the SIRIUS soft‑starter family, it provides controlled ramping and stopping to reduce inrush current and mechanical stress during motor startup and shutdown, helping protect electrical infrastructure and extend motor life. The unit is designed for 460–575 V input and is commonly cataloged as 30 kW at 500 V in many Siemens listings, making it suitable for mid‑to‑large installations where compact, reliable soft starting is required. Its compact open‑frame construction simplifies retrofits and integration alongside other Siemens motor control components, enabling coordinated protection and control within a single panel.
