It provides a manual means of disconnecting power in branch circuits and feeder applications, serving as a required disconnect for motors, HVAC equipment, and other electrical loads. Licensed electricians install this switch as part of NEC-compliant disconnect installations in commercial and industrial facilities. The fused design allows overcurrent protection at the disconnect point, adding a layer of circuit protection beyond the upstream breaker.\u003c\/p\u003e\n\u003cp\u003eThe TH3363 is rated for heavy-duty commercial and industrial applications where a reliable, code-compliant fusible disconnect is required. Typical installations include motor disconnect service for HVAC units, compressors, pumps, and industrial machinery. The NEMA 1 enclosure is suited for dry indoor environments such as mechanical rooms, equipment rooms, and light industrial spaces. This switch is not rated for outdoor or wet locations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e100-amp continuous current rating suitable for heavy motor and equipment loads\u003c\/li\u003e\n  \u003cli\u003e3-pole configuration handles three-phase power systems up to 600 volts\u003c\/li\u003e\n  \u003cli\u003eFusible design provides overcurrent protection integral to the disconnect\u003c\/li\u003e\n  \u003cli\u003eNEMA 1 enclosure rated for dry indoor service\u003c\/li\u003e\n  \u003cli\u003eHeavy-duty construction suited for commercial and industrial environments\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 as a manual disconnect in commercial and industrial electrical systems requiring a 100-amp, 3-pole, 600-volt rated device in a NEMA 1 enclosure.\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 circuit and verify absence of voltage with a meter before opening the enclosure or making any connections. Ensure proper fuse selection matches the load requirements and does not exceed the switch ampere rating. The NEMA 1 enclosure must be installed in a dry, indoor location only.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCurrent Rating\u003c\/strong\u003e: 100 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\u003eSwitch Type\u003c\/strong\u003e: Fusible\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDuty Rating\u003c\/strong\u003e: Heavy Duty\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnclosure Type\u003c\/strong\u003e: NEMA 1 (Indoor)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 783164009132\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: TH3363\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ABB","offers":[{"title":"Default Title","offer_id":51383233806642,"sku":"TH3363","price":622.91,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312672057.png?v=1782590564","url":"https:\/\/voomisupply.com\/products\/abb-th3363-100a-3-pole-600v-fusible-safety-switch-nema-1","provider":"Voomi Supply","version":"1.0","type":"link"}
