Low-Voltage Dry-Type .usGeneral Purpose Dry Type 600 Volts and Below OverviewThe Energy Policy and Conservation Act of 1975 (EPCA), update in the Energy PolicyAct of 2005, authorized the Department of Energy (DOE) to evaluate and set minimumefficiency levels for Low Voltage Distribution Ttransformers. The DOE published a finalrule prescribing new energy conservation standards for distribution transformers. 78 FR23335 (April 18, 2013).10 CFR 431.196: The efficiency of a low-voltage dry-type distribution transformermanufactured on or after January 1, 2016, shall be no less than that required for theirkVA rating in the table below. Low-voltage dry-type distribution transformers with kVAratings not appearing in the table shall have their minimum efficiency level determined bylinear interpolation of the kVA and efficiency values immediately above and below thatkVA rating. All efficiency values are at thirty-five percent of nameplate-rated loadtemperature corrected to 75 C, determined according to the DOE Test Method forMeasuring the Energy Consumption of Distribution Transformers under Appendix A toSubpart K of 10 CFR part 431.Energy Conservation Standards for Low-Voltage Dry-Type Distribution TransformersSingle phaseThree phasekVAEfficiency % [1]kVAEfficiency % 099.23——100099.28Distribution transformer means a transformer that (1) has an input voltage of 34.5 kV orless; (2) has an ouput voltage of 600 V or less; (3) is rated for operation at a frequency of60 Hz; and (4) has a capacity of 10 to 2500 kVA for liquid-immersed units and 15 to 2500kVA for dry-type units.Low voltage dry-type distribution transformer means a distribution transformer that: hasan input voltage of 600 V or less, is air-cooled, and not used oil as a coolant.The following product offering must comply with the table above: Three- and single-phase Step up and step down transformers General purpose ventilated transformers (isolation transformers) Watchdog general purpose ventilated transformers (low temperature rise) Transformers designed for harmonic applications (K-rated, harmonic mitigating, datacenter transformers, etc.) General purpose open core and coil transformersThe following low voltage transformers do not need to comply with the table above: Auto-transformers Drive isolation transformers Non-ventilated transformers Resin encapsulated transformers Buck boost transformers Control transformers (machine tool) Medical isolation panel transformers compliance with UL 1047 (tables 30.1 and 30.2)(SPECIAL IZ — LOW LEAKAGE)14New Three-Phase Offering from Square D — DOE 2016 EX Exceed the efficiency levels from 10 CFR 431.196sized to handle wire ranges to match Square D circuit breakers, switches, Terminalspanelboards, etc.Located to meet NEC bending radius and layout to simplifiy connections IZ Levels to allow for designing with the minimum AIC Panels available In-rush current limited to expand the Square D circuit breaker options at both 125 and250% sizinglevel at 3 dB for all designs, but up to 6–10 dB below on certain units—QUIET SoundQUALITYin. clearance from the rear and side, UL 1561 ALCOVE TESTING ALL 1/2ENCLOSURES TO NOT EXCEED 90 C ON ADJACENT WALLS Four product families of the DOE 2016 EX: General purpose, aluminum and copperwindings, 150 C rise; Watchdog, low temperature rise, aluminum and cooverwindings, 115 or 80 C rise; Two solutions for harominic loads: K-13 Wye secondary,harmonic mitigating transformers and K-9 ZigZag secondary, harmonic cies are determined at the following reference conditions:(1) for no-load losses, at the temperature of 20 C; (2) for load-losses, at the temperature of 75 C and 35% of nameplate load.

This complete package yields considerable savings in installation time and costs.Its NEMA Type 3R enclosure is suitable for both indoor and outdoor use. The transformeris 115 C rise and epoxy-resin encapsulated. The panel section uses Square D brandQO style circuit breakers.NOTE: Mini Power-Zone unit substations are UL 1062 File E92978 Listed.Mini Power-Zone unit substations include factory-installed primary main and secondarymain circuit breakers. Circuit breaker ratings are selected to meet National ElectricalCode requirements and coordinate with transformer magnetizing inrush current. Orderfeeder circuit breakers (QO plug-on type) from your local Schneider Electric distributor.Use Qwik-Gard circuit breakers for required ground fault protection. Tandem circuitbreakers are not permitted.If bolt-on circuit breakers are required instead of plug-on, change the Mini Power-Zonepart number from MPZ to MPZB. The MPZB product line leverages the NQ interior forapplication requirements.The Mini Power-Zone unit substation uses a separate transformer and panel section.This allows the panel section to be removed and wired first if desired. Also thetransformer can be replaced without disturbing the panel section and associated wiring.The new transformer simply slides into the top of the panel section and primary andsecondary leads are reconnected to the main circuit breakers.Catalog No.18k AICFull CapacityTaps[14]EnclosureWeight(lbs)Primary MainCircuit BreakerRating (A)SecondaryMain CircuitBreakerRating (A)Square D Load CenterCircuit Breaker SpacesMaximumMax.
