This disconnect switch is designed to isolate electrical circuits in commercial and industrial applications, providing a safe means of de-energizing equipment during service or maintenance. Licensed electricians install this switch as a service entrance disconnect or branch circuit isolation device where a reliable, code-compliant shutoff is required. The 600-volt rating makes it suitable for higher-voltage distribution panels and motor disconnect applications.\u003c\/p\u003e\n\u003cp\u003eThe THN3365 is used in indoor commercial and light industrial environments where a robust, fusible disconnect is needed. Typical installations include motor circuits, HVAC equipment disconnects, and panel feeder isolation. The NEMA 1 enclosure rating is appropriate for protected indoor locations free from excessive moisture, dust, and corrosive conditions. Electricians working on commercial build-outs, equipment room panels, and mechanical room disconnects commonly specify this switch.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e400-amp continuous current rating for high-load branch and feeder circuits\u003c\/li\u003e\n  \u003cli\u003e3-pole configuration handles three-phase power distribution\u003c\/li\u003e\n  \u003cli\u003e600-volt rating suitable for commercial and light industrial distribution systems\u003c\/li\u003e\n  \u003cli\u003eHeavy duty construction for reliable long-term performance in demanding environments\u003c\/li\u003e\n  \u003cli\u003eNEMA 1 enclosure provides protection in dry indoor installations\u003c\/li\u003e\n  \u003cli\u003eFusible design allows overcurrent protection to be integrated at the disconnect point\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 use in 3-phase indoor commercial and industrial electrical distribution systems requiring a 400-amp, 600-volt, 3-pole disconnect.\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 all upstream power sources and verify absence of voltage with a meter before beginning installation or service. Ensure the enclosure location meets NEMA 1 indoor environmental requirements and that fuse selection matches the connected load and conductor ampacity. Do not exceed the rated voltage or amperage of the switch.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAmperage Rating\u003c\/strong\u003e: 400 amps\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Poles\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVoltage Rating\u003c\/strong\u003e: 600 volts\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnclosure Type\u003c\/strong\u003e: NEMA 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSwitch Type\u003c\/strong\u003e: Heavy Duty Fusible Safety Switch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 78316401138\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: ABB\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: THN3365\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ABB","offers":[{"title":"Default Title","offer_id":51383057482034,"sku":"THN3365","price":3797.31,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312678256.jpg?v=1782586854","url":"https:\/\/voomisupply.com\/products\/abb-thn3365-400a-3-pole-600v-heavy-duty-safety-switch","provider":"Voomi Supply","version":"1.0","type":"link"}
