It features a copper contact construction and accepts a 1\/2 inch stud for secure, low-resistance termination. The terminal measures 3-1\/16 inches in overall length and 1-3\/8 inches in ring width, with a thickness of 11\/32 inches. Licensed electricians and electrical contractors typically install this type of terminal where a bare, high-conductivity copper lug is required and insulation is handled separately by sleeving or the surrounding assembly. It meets CSA, UL Listed, and RoHS compliance standards.\u003c\/p\u003e\u003cp\u003eThis square ring terminal is suited for commercial and industrial electrical installations where compression-terminated copper lugs are specified. It is commonly used on bus bars, transformer connections, switchgear terminations, and heavy-duty panel wiring where a square ring profile provides positive mechanical alignment on the stud. The non-insulated design allows installers to apply heat-shrink or other insulation as required by the application or local code.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eNon-insulated copper contact for high-conductivity bare lug termination\u003c\/li\u003e\n\u003cli\u003eCompression connection style for reliable, cold-weld electrical contact\u003c\/li\u003e\n\u003cli\u003e1\/2 inch stud size for positive mechanical and electrical engagement\u003c\/li\u003e\n\u003cli\u003eOverall length of 3-1\/16 inches and ring width of 1-3\/8 inches\u003c\/li\u003e\n\u003cli\u003eThickness of 11\/32 inches for robust current-carrying capacity\u003c\/li\u003e\n\u003cli\u003eUL Listed, CSA Certified, and RoHS Compliant\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style compression ring terminal for use with 1\/2 inch studs in commercial and industrial electrical panel, switchgear, and transformer wiring applications where a non-insulated copper square ring lug is required.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed electrician in accordance with applicable NEC requirements. De-energize and lock out the circuit before terminating or inspecting any ring lug connection. Use a calibrated compression tool rated for the conductor size and terminal being installed to achieve a proper cold-weld crimp. Do not over-compress or re-crimp a terminal that has already been fully seated.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTerminal Type\u003c\/strong\u003e: Square Ring\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsulation Type\u003c\/strong\u003e: Non-Insulated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Compression\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContact Material\u003c\/strong\u003e: Copper\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStud Size\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-1\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRing Width\u003c\/strong\u003e: 1-3\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 11\/32 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: UL Listed (File E9809), CSA Certified, RoHS Compliant\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: THOMAS BETTS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 31015\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"THOMAS \u0026 BETTS","offers":[{"title":"Default Title","offer_id":51540702232882,"sku":"31015","price":282.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/41726cb7ea7f44f0561a4a6cd6bec587.jpg?v=1785862373","url":"https:\/\/voomisupply.com\/products\/thomas-betts-31015-square-ring-terminal-compression-copper","provider":"Voomi Supply","version":"1.0","type":"link"}
