This relay is designed to switch and route control-circuit signals in industrial and commercial electrical panels, motor control centers, and automation systems. It operates on a DC standard control circuit, making it appropriate for low-voltage DC control applications. Licensed electricians and industrial maintenance technicians install this relay as part of control panel builds, machine interlocks, and relay logic circuits. The compact form factor fits tight enclosures without sacrificing contact flexibility.\u003c\/p\u003e\n\u003cp\u003eThis relay fits into commercial and industrial control panel applications where DC coil voltage is required. Typical installations include motor starter auxiliaries, PLC output interface relays, HVAC equipment control boards, and general-purpose switching in 12 volt DC control circuits. It is packaged individually and suited for single-unit replacement or new panel construction. Applications requiring a reliable multi-contact DC relay in a compact housing will find this unit a straightforward drop-in solution.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3NO plus 1NC contact configuration provides flexible switching in a single relay body\u003c\/li\u003e\n  \u003cli\u003e12 volt DC coil voltage matches common low-voltage DC control circuits\u003c\/li\u003e\n  \u003cli\u003eDC standard control circuit type for use in DC-powered control systems\u003c\/li\u003e\n  \u003cli\u003eCompact footprint at 2.5 inches tall, 2.4 inches wide, and 1.9 inches in length\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.48 pounds, minimizing added load in dense panel layouts\u003c\/li\u003e\n  \u003cli\u003eIndividual packaging supports single-unit field replacement without excess inventory\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation control relay for DC control circuits requiring a 12 volt coil and a 3NO\/1NC contact configuration in commercial and industrial panel applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed electrician in accordance with applicable NEC requirements. De-energize and lock out the control panel before removing or installing the relay. Verify coil voltage and contact ratings against the panel schematic before wiring. Confirm that all control circuit wiring connections are secure and insulated before re-energizing the system.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoil Voltage\u003c\/strong\u003e: 12 volts DC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eContact Configuration\u003c\/strong\u003e: 3NO \/ 1NC\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: 2.5 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: 0.48 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: SCHNEIDER ELECTRIC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: CA3KN31JD\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCHNEIDER ELECTRIC","offers":[{"title":"Default Title","offer_id":51544479367474,"sku":"CA3KN31JD","price":118.27,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/55b15f243d3329b942a7a9d53180ea34_68f5772f-5044-452f-a975-d627b7f85ed7.jpg?v=1785927515","url":"https:\/\/voomisupply.com\/products\/schneider-electric-ca3kn31jd-control-relay-3no-1nc-12vdc","provider":"Voomi Supply","version":"1.0","type":"link"}
