Low Voltage General Purpose Transformers UL Listed, CSA Certified Single Phase Type 1-E Encapsulated Type 1-E general purpose transformers are single phase, resin encapsulated designs suitable for indoor or outdoor applications. It's totally enclosed, nonventilated enclosure make it ideally suited for use in areas that contain dust, moisture, or corrosive fumes. Available in ratings through 25 KVA type 1-E transformers can be mounted in any position for indoor installations and in upright positions only for outdoor installations. UL Listed Three Phase Type 3-E Encapsulated Type 3-E resin encapsulated, 3-phase transformers are available in ratings of 3-75 KVA. Its totally enclosed nonventilated enclosure makes the 3-E ideally suited for outdoor as well as indoor locations. Type 3-E transformers utilize the 185 C insulation system with 115 C rise. 3-E transformers 3-15 KVA are T-T connected. UL listed Single Phase Type 1-V Ventilated 1-V general purpose transformers are single phase ventilated units designed primarily for indoor locations (also for outdoor , 600 volt class with the addition of weathershields). The 1-V utilizes a 220 C insulation system with 150 C rise and is available in ratings of 15167 KVA. 1-V products are compliant to DOE 2016. UL Listed Three Phase Type 3-V Ventilated The 3-phase 3-V ventilated dry-type is available in ratings of 15-750 KVA. Its 220 C insulation system (150 C rise) is selfextinguishing. 3-V enclosures are designed for indoor locations (or outdoor, 600 volt class with addition of weathershields). 3-V products are compliant to DOE 2016. Mounting Units installed outdoors must be mounted in upright position. Efficiency The Micron series of ventilated, three-phase, 600 volt class general purpose distribution transformers meet the DOE 2016 efficiency requirements and federal energy efficiency laws. New distribution transformers installed in the United States are required to meet these energy efficiency requirements as of January 2016. Winding Terminations Primary and secondary windings are terminated in the wiring compartment. Encapsulated units have copper leads or stabs brought out for connections. Micron recommends external cables be rated 90 C (sized at 75 C ampacity) for encapsulated designs. Series-Multiple Windings Series-multiple windings consist of 2 similar coils in each winding which can be connected in series or parallel (multiple). Transformers with series-multiple windings are designated with an "X" or"/" between the voltage ratings. such as primary voltage of "120/240" or "240 X 480". If the series-multiple winding is designated by an "X" the winding can be connected only for a series or parallel. With the"/" designation, a mid-point also becomes available in addition to the series or parallel connection. As an example, a 120 X 240 winding can be connected for either 120 (parallel) or 240 (series), but a 120/240 winding can be connected for 120 (parallel), or 240 (series), or 240 with a 120 mid-point. 2 Contact Micron Industries Corporation: 1.630.516.1222 www.micronpower.com Form: LVGP-16C Courtesy of Steven Engineering, Inc - (800) 258-9200 - sales@steveneng.com - www.stevenengineering.com
General Information Industry Standards All Micron dry-type distribution and control transformers are built and tested in accordance with applicable NEMA, ANSI and IEEE standards. All 600 volt class transformers are UL listed unless otherwise noted. Seismic Qualified The Micron family of dry-type distribution transformers is seismically tested, seismically qualified, and exceeds requirements of the Uniform Building Code (UBC) and California Code Title 24. Frequency Micron standard dry-type distribution transformers are designed for 60 Hz operation. Transformers required for other frequencies must be specifically designed. Overload Capability Short term overload is designed into transformers as required by ANSI. Basically, dry-type distribution transformers will deliver 200% nameplate load for one-half hour; 150% load for one-hour; and 125% load for four-hours without being damaged provided that a constant 50% load precedes and follows the overload. See ANSI C57 .96-01.250 for additional limitations. Continuous overload capacity is not deliberately designed into a transformer because the design objective is to be within the allowed winding temperature rise with nameplate loading. Insulation System & Temperature Rise Industry standards classify insulation systems and rise as shown below: Insulation System Classification Ambient Winding Rise Hot Spot Temp. Class 55 C 10 C 105 C 40 C 80 C 30 C 150 C 40 C 115 C 30 C 185 C 40 C The design life of transformers having different insulation systems is the same – the lower temperature systems are designed for the same life as the higher temperature systems. Sound Levels KVA NEMA Average₁ Sound Level in dB All Micron 600 volt class dry-type distribution transformers are designed to meet NEMA ST-20 levels as listed. 0-9 40 10-50 45 51-150 50 151-300 55 301-500 60 ₁.
