PRODUCT DESCRIPTION
SIEMENS 3RW5055-6TB04 - Soft Starter
This device is a SIEMENS SIRIUS ACT 3RW50 series soft starter designed for controlled motor acceleration and deceleration in industrial applications. It integrates solid-state switching technology to reduce mechanical stress on drive components and mitigate current peaks during motor startup. The unit is suitable for standard three-phase asynchronous motors in applications such as pumps, fans, conveyors, and mixers, operating within a 200-460V AC main circuit voltage range and controlled via 110-250V AC/DC.
