The Hammond HPS Sentinel G general purpose distribution transformer is designed for 600 volts and below, making it ideal for supplying appliance, lighting, heating, motorized machine, and power loads from electrical distribution systems. This transformer features a NEMA 3R enclosure suitable for indoor or outdoor applications, offering cost savings with its bolt-together design. Built with quality non-aging, cold-rolled silicon steel laminations and precision-wound copper or aluminum conductors, it ensures reliable performance and minimizes axial forces during short-circuit conditions. The Sentinel G series meets the latest energy efficiency standards from DOE and NRCan, translating to lower operating costs, decreased cost of ownership, and reduced air conditioning needs. It boasts a standard 10kV BIL rating for increased reliability against voltage spikes and transients, and includes integral floor and wall mounting brackets for faster installation on units up to 45kVA.This is a 3-phase, 45 kVA general purpose distribution transformer from the HPS Sentinel G series. It features a primary voltage rating of 600 Delta V AC and a secondary voltage rating of 480Y/277 VAC, operating at a frequency of 60 Hz. The transformer has an aluminum wound construction and a NEMA 3R enclosure type. It offers a temperature rise of 150°C typical, with a 220°C insulation system. The efficiency rating is 98.4%, and it includes lug/pad connection type and ceiling/floor mounting capabilities. The dimensions are 28.8 inches in height, 25.8 inches in width, and 23.8 inches in depth.
