Control relays of this type serve as switching devices in low-voltage control circuits, allowing a low-power signal to open or close higher-current loads within HVAC, industrial, or electrical panel applications. The 2NC\/2NO contact configuration provides two normally closed and two normally open poles, giving the installer flexibility in control logic. Weighing 0.39 pounds, this compact relay fits standard DIN-rail or panel-mount enclosures. It is installed by licensed electricians or HVAC controls technicians working on motor control, interlock, or sequencing circuits.\u003c\/p\u003e\u003cp\u003eThe CA2KN22B7 is suited for residential and light commercial control panel applications where 24 VAC switching is required. Typical installations include HVAC air-handling unit control circuits, electrical panel interlock schemes, and building automation relay logic. The AC 50\/60 Hz coil design accommodates both North American and international supply frequencies, making it a versatile choice for controls panels that may use global components. Installers working on DDC or standalone HVAC controls will find this relay appropriate for standard 24 VAC class 2 control wiring.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e2NC\/2NO contact arrangement for flexible normally closed and normally open switching logic\u003c\/li\u003e\n\u003cli\u003e24 VAC coil voltage rated for standard HVAC class 2 control circuits\u003c\/li\u003e\n\u003cli\u003eCompatible with both 50 Hz and 60 Hz AC control circuits\u003c\/li\u003e\n\u003cli\u003eCompact, lightweight design at 0.39 pounds for panel space efficiency\u003c\/li\u003e\n\u003cli\u003eSold as individual unit with a package quantity of 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement control relay for 24 VAC, 50\/60 Hz control circuit applications in HVAC, electrical panel, and industrial control systems.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed electrician or qualified HVAC controls technician. De-energize and lock out the control panel before removing or installing the relay, following applicable NFPA 70 (NEC) lockout\/tagout procedures. Verify coil voltage and contact rating against the existing circuit requirements before wiring. Do not exceed the rated contact load for the relay contacts.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoil Voltage\u003c\/strong\u003e: 24 VAC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eControl Circuit Type\u003c\/strong\u003e: AC 50\/60 Hz\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContact Configuration\u003c\/strong\u003e: 2NC\/2NO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.39 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: CA2KN22B7\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCHNEIDER ELECTRIC","offers":[{"title":"Default Title","offer_id":51541511766322,"sku":"CA2KN22B7","price":80.13,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c768934c5d32b253d5a76ca8f9678914_a72d47f8-96c5-4d76-980b-3931563c5f66.jpg?v=1785877931","url":"https:\/\/voomisupply.com\/products\/schneider-electric-ca2kn22b7-control-relay-24-vac","provider":"Voomi Supply","version":"1.0","type":"link"}
