It serves as a disconnect device, allowing qualified electricians to isolate downstream equipment for safe service, maintenance, or emergency shutoff. The switch is fusible, meaning overcurrent protection is built into the enclosure via fuse holders, providing both disconnect and short-circuit protection in a single unit. At 99.803 pounds, this is a substantial industrial-grade enclosure intended for permanent installation in commercial or light industrial electrical systems.\u003c\/p\u003e\n\u003cp\u003eThis safety switch is suited for use in commercial and light industrial facilities where a lockable, visible-blade disconnect is required ahead of motors, HVAC equipment, compressors, or other 3-phase loads. The 3-phase 4-wire configuration supports systems with a neutral conductor, making it appropriate for wye-configured distribution. Installation is typically performed by licensed electricians working on 240-volt distribution systems that require a dedicated fusible disconnect at the equipment level.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFusible disconnect provides overcurrent protection and visible-blade isolation in one enclosure\u003c\/li\u003e\n  \u003cli\u003eRated for 3-phase, 4-wire systems at 240 volts\u003c\/li\u003e\n  \u003cli\u003eHeavy duty construction rated for commercial and light industrial service\u003c\/li\u003e\n  \u003cli\u003eEnclosure dimensions of 6.693 inches x 22.047 inches x 45.276 inches allow for standard panel or wall mounting\u003c\/li\u003e\n  \u003cli\u003eLockable handle supports LOTO (lockout\/tagout) procedures per OSHA requirements\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style heavy duty fusible safety switch for 3-phase 4-wire 240-volt distribution systems in commercial and light industrial electrical installations.\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 all applicable local codes. De-energize the upstream feeder and verify absence of voltage with a calibrated meter before mounting or making any wiring connections. The enclosure weight of approximately 99.803 pounds requires appropriate lifting equipment or a two-person install team for safe positioning and mounting. Verify fuse type and ampere rating are compatible with the connected load before energizing.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVoltage Rating\u003c\/strong\u003e: 240 volts\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePhase Configuration\u003c\/strong\u003e: 3-Phase, 4-Wire\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSwitch Type\u003c\/strong\u003e: Fusible Safety Switch (Disconnect)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnclosure Dimensions (L x W x H)\u003c\/strong\u003e: 6.693 inches x 22.047 inches x 45.276 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 99.803 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eQuantity per Pack\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 88762187256\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: SIEMENS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: HF326NRA\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SIEMENS","offers":[{"title":"Default Title","offer_id":51383297802546,"sku":"HF326NRA","price":14557.32,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312677745.jpg?v=1782592611","url":"https:\/\/voomisupply.com\/products\/siemens-hf326nra-heavy-duty-safety-switch-240v-fusible","provider":"Voomi Supply","version":"1.0","type":"link"}
