It uses an AC coil rated for 120 V at 60 Hz (Siemens lists 110 V AC \/ 50 Hz or 120 V AC \/ 60 Hz), energizing all four contacts to switch loads in control circuits. This configuration makes it suitable for coordinating multiple auxiliary devices, relays, and PLC inputs from a single coil in industrial automation and machine-control panels. Siemens notes this model is no longer available and designates the direct replacement as the 3RH2140-1AK60, ensuring compatibility within the Sirius family. The four normally open contacts provide independent switching paths, simplifying control logic and reducing component count in compact installations; typical applications include motor-control sequences, interlocks, and distribution of control signals in panel assemblies.\u003c\/p\u003e\u003c\/div\u003e","brand":"SIEMENS","offers":[{"title":"New","offer_id":46268093825258,"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-3rh1140-1ak60-contactor-relay-120vac-60hz","provider":"GTG Hardware","version":"1.0","type":"link"}
