It serves as a service entrance disconnect or branch circuit disconnect in industrial and commercial electrical installations. The HF328N provides a means of manually isolating equipment from the power supply, enabling safe maintenance and lockout\/tagout procedures. Licensed electricians install this switch as part of properly engineered power distribution systems where high-ampacity disconnecting means are required by the National Electrical Code.\u003c\/p\u003e\u003cp\u003eThe HF328N is suited for heavy commercial and industrial applications where a robust, high-current fusible disconnect is required. Typical installations include motor disconnect service, large HVAC equipment disconnects, and main or feeder disconnects in distribution panels operating on 240-volt, 3-phase power. This switch is designed for environments where reliable fault protection and manual disconnect capability are critical to system safety and code compliance.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eFusible design provides overcurrent protection coordinated with upstream and downstream protective devices\u003c\/li\u003e\n\u003cli\u003e3-phase, 4-wire configuration supports balanced three-phase loads with neutral\u003c\/li\u003e\n\u003cli\u003e1200-amp continuous rating handles high-capacity electrical loads\u003c\/li\u003e\n\u003cli\u003e240-volt rating suitable for standard North American industrial distribution voltage\u003c\/li\u003e\n\u003cli\u003eHeavy duty construction supports demanding commercial and industrial service conditions\u003c\/li\u003e\n\u003cli\u003eLockout\/tagout capability supports OSHA and NEC safe work practice requirements\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style heavy duty fusible safety switch for 3-phase, 4-wire, 240-volt commercial and industrial power distribution systems requiring a 1200-amp disconnect.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation must be performed by a licensed electrician in accordance with the National Electrical Code and applicable local codes. De-energize and verify absence of voltage on all conductors before working inside the enclosure. Fuses must be selected and sized per NEC Article 430 or the applicable equipment nameplate rating. Do not exceed the marked voltage or amperage ratings of the switch.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage Rating\u003c\/strong\u003e: 240 volts\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmperage Rating\u003c\/strong\u003e: 1200 amps\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\u003eFuse Type\u003c\/strong\u003e: Fusible\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions (L x W x H)\u003c\/strong\u003e: 74.803 inches x 42.913 inches x 11.811 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 350.733 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 78364315035\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: HF328N\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SIEMENS","offers":[{"title":"Default Title","offer_id":51383580131634,"sku":"HF328N","price":27134.18,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312679048.jpg?v=1782601178","url":"https:\/\/voomisupply.com\/products\/siemens-hf328n-safety-switch-3p-240v-1200a-fusible","provider":"Voomi Supply","version":"1.0","type":"link"}
