For other ratings or catalog numbers not shown, or for special enclosure types (including stainless steel), refer to DS-3, DT-3 Ventilated, NEMA 2 enclosure standard Suitable for indoor applications, outdoors when weathershields are also installed Upright mounting only 220 C insulation system 150 C rise standard.

6 115 C or 80 C rise optional Available in single-phase ratings 15 167 kVA, 600 volts primary (DS-3) Available in three-phase ratings 15 1500 kVA and up to 600 volts primary (DT-3)Application DescriptionDOE 2016 compliant energy - efficient transformers are specifically designed to meet the energy efficiency standards set forth in CFR Title 10 Chapter II Part 431, Appendix A of Subpart K 2016 . Surveys have shown that the average loading of low-voltage dry-type distribution transformers, over a 24-hour period, is approximately 35%.

7 DOE 2016 compliant transformers are optimized to offer maximum efficiency at 35% of nameplate rating. The range of products covered by DOE 2016 is:DOE 2016 Product RangeTransformers that are currently specifically excluded from the scope of CFR Title 10 Chapter II Part 431, Appendix A of Subpart K 2016 include: Liquid-filled transformers below 10 kVA Low-voltage dry-type transformers below 15 kVA AC and DC drives transformers Rectifier transformers designed for high harmonics Autotransformers Non-distribution transformers.

9 Short-term overload capability as required by ANSI Meet NEMA ST-20 sound levels Transformer core and coil covered with a fungus-resistant varnish to seal out moisture and other contaminants, and prevent the growth of fungus The core and coil assembly is grounded to the transformer enclosure by means of a visible flexible copper ground strap. The copper ground strap is sized per the NEC to be a grounding conductor. Three-phase DOE 2016 efficient transformers are provided with a bonding ground bar attached to the bottom panel for compliance with NEC (A) Transformers manufacturedin enclosures 939, 940, 942, 943, 944 and 945 are UL Listed to be installed indoors (without weathershields)
