This relay serves as a switching and control device within low-voltage control circuits, routing signals to contactors, motor starters, and other downstream components. Electricians and controls technicians install this relay in panels and enclosures where reliable DC switching is required. The compact form factor measures 2.6 inches in height, 2.4 inches in width, and 1.9 inches in length, making it well suited for tight panel installations.\u003c\/p\u003e\u003cp\u003eThis control relay is designed for use in industrial and commercial control panel applications where a 24-volt DC control circuit is present. Typical scenarios include motor control centers, automation panels, and building automation systems that rely on DC logic signals to energize downstream loads. The 3NO\/1NC contact configuration provides flexible switching arrangements to suit a variety of control logic needs in both new installations and replacement service work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e24 volt DC coil voltage for compatibility with standard DC control circuits\u003c\/li\u003e\n\u003cli\u003e3 normally open and 1 normally closed contact arrangement for versatile switching logic\u003c\/li\u003e\n\u003cli\u003eCompact dimensions (2.6 x 2.4 x 1.9 inches) suited for space-constrained enclosures\u003c\/li\u003e\n\u003cli\u003eLightweight construction at 0.5 pounds for easy panel mounting\u003c\/li\u003e\n\u003cli\u003eDC standard control circuit type for stable, low-noise operation in electronic control systems\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement control relay for DC control circuit applications requiring a 24 volt coil and a 3NO\/1NC contact configuration in industrial and commercial panel assemblies.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed electrician or qualified controls technician. De-energize and lock out the control panel before removing or installing the relay in accordance with NFPA 70E electrical safety procedures. Verify coil polarity and contact ratings match the circuit requirements before energizing. Confirm the relay is securely seated in its base or DIN-rail mount before restoring power.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoil Voltage\u003c\/strong\u003e: 24 volts DC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContact Configuration\u003c\/strong\u003e: 3 normally open (NO), 1 normally closed (NC)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eControl Circuit Type\u003c\/strong\u003e: DC Standard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 2.6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 2.4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 1.9 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SCHNEIDER ELECTRIC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: CA3KN31BD3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCHNEIDER ELECTRIC","offers":[{"title":"Default Title","offer_id":51542548021554,"sku":"CA3KN31BD3","price":111.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/55b15f243d3329b942a7a9d53180ea34.jpg?v=1785903400","url":"https:\/\/voomisupply.com\/products\/schneider-electric-ca3kn31bd3-control-relay-3no-1nc-24-vdc","provider":"Voomi Supply","version":"1.0","type":"link"}
