Product Description P/N: 3RW4427-1BC34
Description
The Siemens 3RW4427-1BC34 is a SIRIUS soft starter designed to provide controlled motor starting and stopping for three-phase industrial motors. It supports standard operation up to 82 A (60 hp) at 460 V and inside-delta configurations up to 142 A (100 hp), reducing mechanical stress and electrical peaks during motor startup. Built for reliable operation in demanding environments, it operates within a 200–460 V AC power range and uses screw terminal connections for secure installation.
