It is designed for commercial and industrial electrical distribution systems where a reliable, code-compliant disconnect is required. The switch ships in a NEMA 1 enclosure for indoor installations and supports a 4-wire configuration. Licensed electricians install this switch as a service entrance disconnect, motor disconnect, or branch circuit isolation point. Key ratings include 3 horsepower at 240 Vac single-phase under NEC standard fusing and 7.5 horsepower at 240 Vac three-phase under NEC standard fusing, with higher horsepower ratings available using time-delay fusing.\u003c\/p\u003e\n\u003cp\u003eThe th4322 is suited for light commercial and industrial applications where a robust indoor fusible disconnect is needed. Typical installation scenarios include motor branch circuits, HVAC equipment disconnects, and panel feeder isolation in commercial buildings. The switch accommodates copper or aluminum conductors ranging from 12 to 2 AWG, making it compatible with a broad range of field wiring conditions. It carries GSA compliance, making it eligible for government and federally funded projects.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e60-amp, 3-pole fusible disconnect rated for 240 volts AC and 250 volts DC\u003c\/li\u003e\n  \u003cli\u003eNEMA 1 indoor enclosure for general-purpose protected environments\u003c\/li\u003e\n  \u003cli\u003eAccepts copper or aluminum conductors from 12 to 2 AWG\u003c\/li\u003e\n  \u003cli\u003eTime-delay fusing supports up to 10 hp single-phase and 15 hp three-phase at 240 Vac\u003c\/li\u003e\n  \u003cli\u003eGSA-compliant for use on government and federally funded projects\u003c\/li\u003e\n  \u003cli\u003eHeavy-duty category construction suited for commercial and industrial service\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 commercial and industrial electrical distribution applications requiring a 60-amp, 3-pole, 240-volt indoor 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 all applicable local codes. De-energize the upstream circuit and verify absence of voltage with a meter before beginning any wiring work. Ensure the enclosure is mounted securely to a vertical surface with the operating handle accessible and unobstructed. Fuse selection must match the load type and motor horsepower rating per NEC requirements for the specific application.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAmperage\u003c\/strong\u003e: 60 amps\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVoltage\u003c\/strong\u003e: 240 volts AC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDC Voltage Rating\u003c\/strong\u003e: 250 volts DC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoles\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWires\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFusing\u003c\/strong\u003e: Fusible\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnclosure\u003c\/strong\u003e: NEMA 1 (Indoor)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWire Range (Cu\/Al)\u003c\/strong\u003e: 12 to 2 AWG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMotor Rating 240 Vac NEC Standard 1-Phase\u003c\/strong\u003e: 3 hp\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMotor Rating 240 Vac NEC Standard 3-Phase\u003c\/strong\u003e: 7.5 hp\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMotor Rating 240 Vac Time Delay 1-Phase\u003c\/strong\u003e: 10 hp\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMotor Rating 240 Vac Time Delay 3-Phase\u003c\/strong\u003e: 15 hp\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMotor Rating 250 Vdc\u003c\/strong\u003e: 10 hp\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCategory\u003c\/strong\u003e: Heavy Duty\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGSA Compliance\u003c\/strong\u003e: Yes\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: th4322\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ABB","offers":[{"title":"Default Title","offer_id":51268155965746,"sku":"TH4322","price":284.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/308912860.jpg?v=1780700634","url":"https:\/\/voomisupply.com\/products\/abb-th4322-heavy-duty-fusible-safety-switch-60a-3p-240v","provider":"Voomi Supply","version":"1.0","type":"link"}
