Product description

The Siemens 3RW2226-1AA05 is a solid-state motor starter designed for soft starting of three-phase motors. It provides a smooth ramp-up of motor speed, reducing mechanical stress and electrical inrush current. This starter is rated for 28A and can handle motors up to 15 kW at 400V, with a derating to 40°C.

This soft starter is ideal for applications where high starting torques can damage equipment or cause power surges, such as conveyor systems, pumps, compressors, and fans. It offers improved reliability and extended motor life compared to direct-on-line starters.
