Siemens 3RW3017-1BB14 SIRIUS Soft Starter S00 12.5A 5.5kW 200-480V

The Siemens 3RW3017-1BB14 is a SIRIUS series soft starter in size S00, rated at 12.5 A and 5.5 kW at 400 V / 40 °C. It controls the starting and stopping of 3-phase AC motors by ramping voltage through integrated thyristors, and includes a built-in bypass contact system for reduced heat dissipation during continuous operation. The control supply accepts 110-230 V AC/DC, making it compatible with a wide range of control circuits.
