Housed in the compact S00 size with screw-terminal connections, it provides front IP20 protection for panel mounting in control cabinets. This four-pole relay module is designed to be driven by a DC control signal to switch auxiliary circuits or drive interposed relays in automation and machine-control schemes. Ideal for control panels in automation environments, it enables multiple independent signaling paths from a single coil and integrates with Siemens Sirius systems and standard DC control voltages. The 3RH1140-1BG40 configuration corresponds to four normally open contacts, enabling signaling and interlock and control functionality within IEC-based control architectures. When selecting this part, ensure coil voltage compatibility (125 V DC) and match the S00 housing and screw-terminal connections to your installation requirements.\u003c\/p\u003e\u003c\/div\u003e","brand":"Siemens","offers":[{"title":"New Surplus No Box","offer_id":46268094120170,"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-3rh1140-1bg40-three-phase-soft-starter","provider":"GTG Hardware","version":"1.0","type":"link"}
