Product description

The Siemens 3RW4075-6BB34 is a SIRIUS soft starter designed for smooth starting and stopping of three-phase AC motors. It has a rated current of 315 A and is suitable for motors up to 250 HP at 460V. The input voltage range is 200-460V AC, and it features screw terminals for connection. This is a phased-out product with the SIRIUS 3RW5 series as its successor.
