It carries a NEMA 1 enclosure rating, making it suitable for indoor installations in clean, dry environments. The DTU323 is rated for 15 horsepower at single-phase 240 Vac and 30 horsepower at three-phase 240 Vac, handling a wide range of motor and equipment loads. Licensed electricians install this switch as a local lockable disconnect in compliance with NEC requirements for motor branch circuits and equipment disconnect applications.\u003c\/p\u003e\n\u003cp\u003eThe DTU323 is used in residential, commercial, and light industrial settings where a non-fusible indoor disconnect is required. Common applications include motor disconnects for HVAC equipment, air compressors, pumps, and other three-phase or single-phase machinery. Its 3PDT contact form and high amperage rating make it a practical fit for equipment panels and machinery disconnects where overcurrent protection is handled upstream by a breaker or fused panel. The NEMA 1 enclosure limits use to protected indoor locations free from dust, moisture, and corrosive environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNon-fusible design — overcurrent protection handled by upstream device\u003c\/li\u003e\n  \u003cli\u003e100-amp rating with 3-pole, 3PDT contact configuration\u003c\/li\u003e\n  \u003cli\u003eNEMA 1 indoor enclosure for clean, dry installation environments\u003c\/li\u003e\n  \u003cli\u003eRated 15 HP at single-phase 240 Vac and 30 HP at three-phase 240 Vac\u003c\/li\u003e\n  \u003cli\u003eAlso rated 20 HP at 250 Vdc for both single- and three-phase configurations\u003c\/li\u003e\n  \u003cli\u003eRoHS Compliant and UL Listed\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation non-fusible safety switch for indoor motor disconnect applications requiring a 100-amp, 3-pole 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 applicable local codes. De-energize and lock out the upstream circuit before mounting or wiring the switch. Verify that the enclosure location is dry and protected from physical damage, as the NEMA 1 rating does not provide protection against moisture or dust. Confirm that upstream overcurrent protection is properly sized for the connected load, since this switch provides no internal fusing.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAmperage\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\u003eContact Form\u003c\/strong\u003e: 3PDT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFused\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHorsepower (1-Phase)\u003c\/strong\u003e: 15 HP at 240 Vac, 20 HP at 250 Vdc\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHorsepower (3-Phase)\u003c\/strong\u003e: 30 HP at 240 Vac, 20 HP at 250 Vdc\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNEMA Enclosure Rating\u003c\/strong\u003e: NEMA 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 10.3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 12.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 33 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 36 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCertifications\u003c\/strong\u003e: UL Listed, RoHS Compliant\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: SQUARE D\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: DTU323\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCHNEIDER ELECTRIC","offers":[{"title":"Default Title","offer_id":51541066907954,"sku":"DTU323","price":1830.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/53555af75340951fc0fe1557beb0d3f4.jpg?v=1785868064","url":"https:\/\/voomisupply.com\/products\/square-d-dtu323-100a-3-pole-non-fusible-safety-switch","provider":"Voomi Supply","version":"1.0","type":"link"}
