Built for 3-pole, single-phase wiring applications, this switch uses a key-lock mechanism to restrict unauthorized operation  -  a critical feature in commercial, institutional, and light industrial settings where access control is required. At 33.3mm wide, it fits standard device boxes and plates. Licensed electricians install this type of switch where NEC compliance and specification-grade durability are required.\u003c\/p\u003e\n\u003cp\u003eThis switch is suited for commercial and light industrial installations where lighting or fan circuits require controlled, restricted switching. The key-lock design prevents tampering or accidental switching by unauthorized personnel, making it a common choice for schools, hospitals, retail spaces, and public facilities. The wide voltage range of 120 to 277 VAC accommodates both standard single-phase branch circuits and higher-voltage commercial lighting systems without requiring a different device.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eKey-lock switch operation restricts unauthorized use on sensitive or safety-critical circuits\u003c\/li\u003e\n  \u003cli\u003e20-amp rating handles standard and heavy-duty branch circuit loads\u003c\/li\u003e\n  \u003cli\u003e120 to 277 VAC operating range covers residential through commercial lighting voltages\u003c\/li\u003e\n  \u003cli\u003e3-pole, single-phase configuration for three-way switching applications\u003c\/li\u003e\n  \u003cli\u003eSpecification grade construction meets commercial project specs and inspector requirements\u003c\/li\u003e\n  \u003cli\u003eMeets FULS standards and carries cULus listing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style specification-grade replacement or new-installation three-way key-lock switch for commercial and light industrial branch circuit applications rated up to 20 amps and 277 VAC.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize the branch circuit at the panel and verify absence of voltage with a meter before wiring. This is a three-way device and requires correct traveler and common terminal wiring  -  consult the wiring diagram supplied with the device. Do not exceed the 20-amp or 277 VAC ratings.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSwitch Type\u003c\/strong\u003e: Three Way\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSwitch Operation\u003c\/strong\u003e: Key Lock\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVoltage Rating\u003c\/strong\u003e: 120 to 277 VAC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAmperage Rating\u003c\/strong\u003e: 20 amps\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoles\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePhase\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Specification\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 33.3mm (1.95 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 1.8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 4.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.22 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards Met\u003c\/strong\u003e: FULS, cULus\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: COOPER WIRING DEVICES\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: AH1223L\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EATON","offers":[{"title":"Default Title","offer_id":67910260359474,"sku":"AH1223L","price":36.85,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/39fe694333c8d369a7385d26fe342afc.jpg?v=1791197020","url":"https:\/\/voomisupply.com\/products\/cooper-wiring-devices-ah1223l-key-lock-three-way-switch","provider":"Voomi Supply","version":"1.0","type":"link"}
