It is rated for 63 A and 30 kW at 400 V, supports a 200–480 V AC supply range, and uses a 24 V control supply (24 V AC\/DC) with screw terminals for reliable, straightforward wiring. Designed for ambient temperatures up to 40 °C, the unit also features an integrated bridging contact system to simplify wiring and improve fault tolerance in standard automation installations. Typical applications include starting and soft-start control of fans, pumps, conveyors and other medium-power motors in industrial environments, where gradual ramping of motor voltage supports smoother operation and extended motor life. As a member of the SIRIUS soft starter family, 3RW3037-1BB04 combines Siemens engineering with compact packaging designed for panel installations in standard automation cabinets.\u003c\/p\u003e\u003c\/div\u003e","brand":"SIEMENS","offers":[{"title":"New","offer_id":46268141207786,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/8039\/3450\/files\/GTG-STOCK-017.png?v=1788727429","url":"https:\/\/gtghardware.com\/products\/siemens-3rw3037-1bb04-soft-starter","provider":"GTG Hardware","version":"1.0","type":"link"}
