Built around a malleable iron enclosure that meets ASTM A47-77 standards and is zinc electroplated with dichromate and epoxy powder coating, this switch is engineered to prevent arcing inside ignitable atmospheres during connect and disconnect operations involving lighting and light power loads. A licensed electrician installs it in classified hazardous locations where ignitable vapors, gases, or highly combustible dusts may be present. The front-operated lever actuator is made from Nylon 6\/6, and the unit ships as a single-gang, single-piece assembly.\u003c\/p\u003e\n\u003cp\u003eThis switch is intended for use in Class I Division 1 and 2 Group C and D environments, Class II Division 1 and 2 Group E, F, and G environments, and Class III locations. Typical installation sites include chemical plants, petrochemical plants, refineries, and other process industries where the NEC requires explosionproof or dust-ignitionproof enclosures. The 3\/4-inch hub accommodates standard conduit entries common in industrial wiring systems, and the single-gang box type integrates into existing classified-area panel arrangements.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eExplosionproof and dust-ignitionproof construction rated for Class I Div 1 and 2 and Class II Div 1 and 2 hazardous locations\u003c\/li\u003e\n  \u003cli\u003eSmooth ground mating surfaces on the cover-to-enclosure joint maintain a flame-tight seal\u003c\/li\u003e\n  \u003cli\u003eStainless steel hex head cap screw secures the cover to the mounting enclosure for reliable closure\u003c\/li\u003e\n  \u003cli\u003eSmooth rounded integral bushing in each hub protects conductor insulation during pull-through\u003c\/li\u003e\n  \u003cli\u003eExternal mounting lugs on the enclosure simplify surface installation\u003c\/li\u003e\n  \u003cli\u003eFront-operated lever handle with close-tolerance threaded stainless steel shaft; lockable in ON or OFF position to meet explosionproof requirements\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style explosionproof switch for hazardous-location wiring systems in industrial and process-industry applications requiring NEMA 7CD\/9EFG rated enclosures and UL 894\/1203 listed components.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation must be performed by a licensed electrician in accordance with NEC Article 500 and applicable local codes governing hazardous classified locations. De-energize and lock out the circuit before opening any conduit or enclosure in the classified area. Ensure all conduit seals required by the classification are installed per code before energizing. Do not modify the enclosure, hub threads, or cover mating surfaces, as any alteration may compromise the explosionproof integrity of the assembly.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVoltage Rating\u003c\/strong\u003e: 120 to 277 volts AC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCurrent Rating\u003c\/strong\u003e: 20 amps\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eContact Configuration\u003c\/strong\u003e: 2-Pole\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: Feed Through\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOperator Type\u003c\/strong\u003e: Front Operated Lever\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBox Type\u003c\/strong\u003e: Single Gang\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHub Size\u003c\/strong\u003e: 3\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnclosure Classification\u003c\/strong\u003e: Class I Div 1 and 2 Group C D, Class II Div 1 and 2 Group E F G, Class III, NEMA 7CD\/9EFG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConstructional Feature\u003c\/strong\u003e: Dust Ignitionproof, Explosionproof\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnclosure Material\u003c\/strong\u003e: ASTM A47-77 Zinc Electroplated Dichromate Epoxy Powder Coated Malleable Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eActuator Material\u003c\/strong\u003e: Nylon 6\/6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApproval\u003c\/strong\u003e: UL 894\/1203\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 7.6 inches L x 5.7 inches W x 4.8 inches H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 5.3 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCountry of Origin\u003c\/strong\u003e: MX\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: APPLETON\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: EFSC175-F2\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"APPLETON","offers":[{"title":"Default Title","offer_id":51284028817714,"sku":"EFSC175-F2","price":376.77,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309279619.jpg?v=1781066549","url":"https:\/\/voomisupply.com\/products\/appleton-efsc175-f2-explosionproof-tumbler-switch-20a","provider":"Voomi Supply","version":"1.0","type":"link"}
