It accepts a 480 V delta primary and delivers a 208Y\/120 V secondary, enabling safe stepping down of three‑phase 480 V service to 208 V line‑to‑line and 120 V line‑to‑neutral loads for control panels, switchgear, and auxiliary circuits. This DOE 2016 energy‑efficient model operates at 60 Hz and carries a 115°C rise rating, reflecting its insulation and thermal design for ventilated indoor environments. The EX15T3HF family includes variants (for example EX15T3HFNLP) that differ in enclosure and mounting configurations, so verifying the exact part number is important for fit and installation. In typical electrical room or equipment‑rack installations, it provides reliable, low‑maintenance power conversion from 480 V to the lower voltage distribution needed by controls, lighting, and auxiliary equipment, while remaining compatible with standard Square D protective devices and panel interfaces. \u003c\/p\u003e\u003c\/div\u003e","brand":"Square","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":46259006832874,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/8039\/3450\/files\/GTG-STOCK-012.png?v=1788727428","url":"https:\/\/gtghardware.com\/products\/schneider-electric-ex15t3hf-dry-type-transformer","provider":"GTG Hardware","version":"1.0","type":"link"}
