General Purpose Dry Type 600 Volts andBelowOverviewschneider-electric.usGeneral Purpose Dry Type 600 Volts and Below OverviewPublic Law 109-58 of the Energy Policy Act of 2005 authorized the Department of Energyto evaluate and set minimum Efficiency Levels for Low Voltage DistributionTransformers.According to Department of Energy Federal Registry Final Rule 10 CFR Part 429 and431, Low-Voltage Dry-Type Distribution Transformers, the efficiency of a low-voltage,dry-type, distribution transformer manufactured on or after January 1, 2007 (and prior toJanuary 1, 2016), shall be no less than that required for its kVA rating in the Table 1below. In April 2013, the Department of Energy ruled the efficiency of a low-voltage drytype distribution transformers manufactured on or after January 1, 2016, shall be no lessthan that required in Table 4 below.Prior to January 1, 2016 Table 1Energy Conservation Standards for Low-VoltageDry-Type Distribution TransformersSingle phaseThree 950098.7——75098.8——100098.9After January 1, 2016 Table 4Energy Conservation Standards for Low-VoltageDry-Type Distribution TransformersSingle phaseThree ��100099.28Must Comply with Tables AboveDistribution transformers include three-phase and single-phase, General PurposeVentilated Transformers, Watchdog Low Temperature Rise Ventilated Transformers,transformers designed for harmonic loads (K-rated and harmonic mitigating).Exempt From Tables AboveTransformers excluded from the distribution transformers: Resin Encapsulated (Sealed)Transformers, Non-Ventilated Transformers, Auto-Transformers, and Drive IsolationTransformers.New Three Phase Product Offering – EXComplies with Table 4, designed to complete the electrical distribution systemincorporating other Schneider Electric equipment.range on terminals equivalent to circuit breakers, switches, panelboards, and Wireswitchboards Inrush design to allow PowerPact circuit breakers to be set up to energize thetransformer IZ levels to limit let through currentAvailable in the following family of products: Three Phase General Purpose – Aluminum and Copper Windings– Sound level 3dB below ST-20 standard– 1/2 inch minimum clearance from rear and sides Watchdog Low Temperature Rise – Aluminum and Copper Windings– 80 C Rise – reduction of BTUs at 75% and 100% loading points Harmonic Solution – Aluminum and Copper Windings– K-9 rated, to meet K-7 harmonic load profiles– Zigzag secondary to limit voltage distortion during harmonic loads and improvedefficiency at load levels above 50%14TRANSFORMERS[1]Efficiencies 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 percent of nameplate load.(Source: Table 4–2 of National Electrical Manufacturers Association (NEMA) Standard TP–1–2002, Guide for Determining Energy Efficiency for Distribution Transformers.)14-2 2016 Schneider ElectricAll Rights Reserved3/24/2016Courtesy of Steven Engineering, Inc. - (800) 258-9200 - sales@steveneng.com - www.stevenengineering.com

Mini Power-Zone Unit SubstationGeneral Purpose Dry Type 600 Volts andBelowClass 7400 / Refer to Catalog 7400CT0901schneider-electric.usSealed, Mini Power-Zone Unit SubstationThe Square D brand Mini Power-Zone unit substation from Schneider Electricprovides the answer to requirements for a portable, compact power supply for smallloads. 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.Table 14.11: Plug On Circuit BreakersCatalog No.18k AICFull CapacityTaps[12]EnclosureWeight(lbs)Primary MainCircuit BreakerRating (A)SecondaryMain CircuitBreakerRating (A)Square D Load CenterCircuit Breaker SpacesMaximumMax.
