With a 24 V DC coil, it switches three-phase loads up to 7.5 kW at 400 V and carries a rated main current of 17 A. The unit includes one normally open and one normally closed auxiliary contact (1 NO + 1 NC) for control wiring, and it uses screw-terminal connections in a compact S0 frame for easy panel mounting. This device belongs to Siemens’ SIRIUS 3RT2 family and is intended for motor start\/stop duties in automation, such as conveyors, pumps, fans, and processing equipment, where reliable AC-3 rated switching of motor loads is required. The 3RT2025-1BB40 is suitable for panel builders seeking a compact, integrated solution with a built-in auxiliary contact to simplify control circuits without needing extra contact blocks. Verify regional catalog variants for exact mounting dimensions and terminal layout, but the core specs—3-pole, AC-3e\/AC-3 operation, 24 V DC coil, 17 A, 7.5 kW at 400 V, 1 NO + 1 NC auxiliary—remain consistent across official listings.\u003c\/p\u003e\u003c\/div\u003e","brand":"Siemens","offers":[{"title":"New","offer_id":46268117778666,"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-3rt2025-1bb40-3-pole-contactor","provider":"GTG Hardware","version":"1.0","type":"link"}
