DESCRIPTION

HPS Sentinel® general purpose distribution transformers are rated for 600 volts and below. They are generally used for supplying appliance, lighting, heating, motorized machine and power loads from electrical distribution systems. For non-linear loads, all standard energy efficient distribution transformers have to be derated to allow for additional heat due to harmonic losses.

HPS Sentinel® Distribution Transformer, Energy Efficient General Purpose, 480 Delta VAC Primary, 208Y/120 VAC Secondary, 112.5 kVA, 60 Hz, 3, Lug/Pad, Floor Mount, 220 deg C, NEMA 3R, 30 deg C, 98.2% Efficiency, 38 in H x 26 in W x 25 in D
