Product Description

7400CT1901

The Square DTM Distribution Transformer is designed to supply power throughout the building. The transformer permits the use of multiple voltages in the design of the system.
Some advantages to designing a system with low voltage transformers:
· Distributes a voltage higher than required by the load to limit wire losses and voltage drop
· Addition of source impedance to the system, reducing common overcurrent at normal voltages
· Mitigates harmonics through an internal magnetic circuit
· Allows system grounding closer to the load, reducing capacitive noise
· Can be designed for any output voltage that is required.
A few disadvantages to designing a system with low voltage distribution transformers:
· Reduces overall efficiency of the system due to internal losses within the transformer
· Added heat to the building if installed indoors and in the HVAC system.
The impact on the efficiency of the system and the concerns for improvements in the market for energy consumption have led to low voltage distribution transformers being regulated through the Energy Policy and Conservation Act (United States) and Natural Resources (Canada).
Below are the efficiency ratings of Three-Phase Low Voltage Dry-Type Distribution Transformers:

Three-Phase kVA 15 30 45 75 112.5 150 225 300 500 750 1000

Efficiency (%) 97.89 98.23 98.40 98.60 98.74 98.83 98.94 99.02 99.14 99.23 99.28

NOTE: All efficiency values are at 35% of nameplaterated load, determined according to the U.S. Department of Energy (DOE) Test Method for Measuring the Energy Consumption of Distribution Transformers under Appendix A to Subpart K of 10 CFR part 431.

EXN Energy Efficient Transformer Family
Square D transformers manufactured by Schneider ElectricTM are optimized for performance, including the following components:
· Coil--Designed to reduce the losses with customized wire configurations used exclusively by Schneider Electric. Computer-controlled winding equipment minimizes variability during the winding process. Aluminum conductors are standard with copper conductors available as a factory option.
· Insulation System--The system consists of a conductor wrap or coating, layer insulation, air gap spacing, and varnish material. The system is UL listed for a specific maximum temperature for average temperature rise, hot spot, and ambient temperature. Schneider Electric's EXN family of transformers have a 428°F (220°C) insulation system, with an average temperature rise maximum of 302°F (150°C).
· Core--EXN Transformers are designed with high-grade grain oriented, nonaging silicon steel laminations with high magnetic permeability, low hysteresis, and low eddy current losses. The computer-aided process allows the design to keep the magnetic flux densities well below the saturation point. The laminations are carefully and evenly stacked via distributive gap laminations, then clamped together to ensure an efficient magnetic circuit while providing a quiet quality offering of low voltage transformers.
· Terminals--Sized to allow the lugs to align with all corresponding Schneider Electric equipment (such as circuit breakers, switches, panelboards, switchboards, etc.). The terminal positioning separates the Primary and Secondary terminals and meets the National Electrical Code® (NEC®) minimum wire bending requirements. Lugs are not shipped with the transformer. This allows the installer the flexibility to order what is needed to meet any distribution system requirements. NOTE: Both mechanical and compression lug kits are available from Schneider Electric.
Terminals are standardized to National Electrical Manufacturers Association® (NEMA®) two-pole pad dimensions.
Codes and Standards
NEMA ST-20--100% routine testing prior to shipment; other ST-20 testing available at time of order, to be included when shipped.
UL1561 and CSA22.2 No. 47--Third party Certified by UL ­ File E6868; cULus Labeled
Energy Efficient Registration--Department of Energy 10 CFR 429; Natural Resources Canada ­ via UL
Manufactured in ISO 9001 Facilities--Product Environmental Profile ­ RoHS/ REACH

When voltage is applied to the input winding of a transformer, there can be a brief period of inrush current until the transformer core stabilizes. Inrush lasts approximately six power cycles, or about 0.1 seconds. The magnitude of the inrush varies depending on when the switch closes on the power wave, so that inrush can be anywhere from zero to greater than the full load current rating of the transformer.
In addition, the impedance of the supply system can influence the amount of inrush current the transformer can draw. To avoid tripping circuit breakers or blowing fuses on the primary side of the transformer during energizing, careful coordination of fuse sizes or circuit breaker handle ratings and magnetic trip settings is essential. This coordination requires information about maximum possible inrush to be expected from the particular transformer in question.
In order to provide optimal coordination and prevent possible inrush nuisance tripping, the primary overcurrent protection should be adjusted based on the maximum inrush current. This will result in the primary overcurrent protection exceeding the 125% allowance in the NEC for primary-only protection, and secondary protection will be required.
