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.
