Equipped with a 4NO (four normally open) contact configuration and a 110\/120 VAC coil, this relay interfaces with control-voltage circuits operating at 50 or 60 Hz. The IP20-rated enclosure and threaded terminal connections make it well suited for panel-mount applications where personnel protection and secure wiring are priorities. Licensed HVAC\/R technicians, industrial electricians, and controls specialists typically specify this component in motor control centers, machine control panels, and automation systems.\u003c\/p\u003e\n\u003cp\u003eThis relay is intended for commercial and industrial installations where a dedicated control relay is needed to multiplex or amplify switching signals within a panel. The snap-on DIN-rail mounting style allows for straightforward integration alongside contactors, overload relays, and other SIRIUS-series components. Its operating temperature range of -25 to 60 degrees C makes it viable in both indoor climate-controlled enclosures and unheated industrial spaces. The 4NO contact form supports applications that require multiple simultaneous make contacts from a single coil energization.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e4NO contact form provides four independently wired normally open switching paths from one coil\u003c\/li\u003e\n  \u003cli\u003e110\/120 VAC coil voltage matches standard North American control-circuit voltage levels\u003c\/li\u003e\n  \u003cli\u003eSnap-on DIN-rail mounting for fast, tool-free installation alongside other SIRIUS-series devices\u003c\/li\u003e\n  \u003cli\u003eIP20 enclosure rating guards against finger contact with live parts in open panel environments\u003c\/li\u003e\n  \u003cli\u003eThreaded terminal connections ensure vibration-resistant, code-compliant wiring terminations\u003c\/li\u003e\n  \u003cli\u003eCertified to CCC, CE, CSA, EAC, EN 60947, IEC 60947, and UL standards for broad market acceptance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style contactor control relay for use within SIRIUS-series modular control panel assemblies where a 4NO, 110\/120 VAC coil relay is required.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified industrial electrician in accordance with the NEC and applicable IEC 60947 guidelines. De-energize and lock out the control panel completely before removing or installing this relay. Snap the unit firmly onto the DIN rail and verify all threaded terminal screws are tightened securely before re-energizing. Do not exceed the rated contact current or apply voltages outside the specified coil and contact ranges.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eContact Form\u003c\/strong\u003e: 4NO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoil Voltage\u003c\/strong\u003e: 110\/120 VAC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFrequency Rating\u003c\/strong\u003e: 50\/60 Hz\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eContact Rating\u003c\/strong\u003e: 6\/1 A at 230\/690 VAC, 10\/1 A at 24\/220 VDC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnclosure Type\u003c\/strong\u003e: IP20\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTemperature Rating\u003c\/strong\u003e: -25 to 60 degrees C\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMounting Type\u003c\/strong\u003e: Snap-On DIN Rail\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTerminal Type\u003c\/strong\u003e: Threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDimensions\u003c\/strong\u003e: 2.264 inches H x 1.772 inches W x 2.835 inches D\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards and Approvals\u003c\/strong\u003e: CCC Certified, CE Marked, CSA Certified, EAC Rated, EN 60947 Rated, IEC 60947, UL Listed\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SIEMENS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 3rh1140-1ak60\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SIEMENS","offers":[{"title":"Default Title","offer_id":51268811751730,"sku":"3RH1140-1AK60","price":298.22,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/308911886.jpg?v=1780706485","url":"https:\/\/voomisupply.com\/products\/siemens-3rh1140-1ak60-contactor-control-relay-4no","provider":"Voomi Supply","version":"1.0","type":"link"}
