The purpose of this notification is to inform you that Siemens is phasing out the following two soft starters:  Sirius 3RW4 and ERW/40 S6/12. These products have reliably been facilitating motor starting for approximately 20 years.  However, advanced technology in digitalization has placed more challenging demands on motor starters.

  2. Sirius 3RW44 & Sirius 3RW40 S6/S12 + Accessories & Spare Parts:  October 1, 2022

  • Milestone PM490:  Total discontinuation is scheduled for one year later in October 2023

Important PLM Phase-Out Timeline:

  1. October 1, 2019:  Siemens transitioned the above product families to plan for obsolescence (PM400).
