Description
The Hammond Power Solutions (HPS) SG3A0075BK dry type transformer is a high-efficiency general-purpose distribution transformer designed for 600 volts and below. It is ideal for powering appliances, lighting, heating systems, motorized machines, and various power loads from electrical distribution networks. With a 208 Delta VAC primary and a 480Y/277 VAC secondary, this transformer delivers 75 kVA of power at 60 Hz frequency, making it suitable for a wide range of industrial and commercial applications.
Built for indoor and outdoor use, the transformer features a DH3-N3R enclosure, providing protection against rain, sleet, and snow. It incorporates aluminum windings and precision-cut, cold-rolled silicon steel laminations, ensuring superior performance and efficiency. The 98.6% energy efficiency rating meets the latest U.S. DOE 10 CFR Part 431 efficiency standards, reducing energy consumption and operating costs. Front-accessible high and low-voltage terminals with aluminum and copper-compatible connectors allow for quick and easy cable installation.
Key Features of HPS SG3A0075BK 480 volts Transformer:
• Complies with DOE 10 CFR Part 431 efficiency standards.
• Precision-wound conductors reduce axial forces during short-circuit conditions.
• Moisture-resistant core coating enhances durability.
• Side knockouts and bottom conduit entry for simplified wiring.
• Robust core and coil interface improves short-circuit performance.
