Product Details

Brand Name

HPS Sentinel®

Type

Energy Efficient General Purpose

Description

HPS Sentinel® general purpose distribution transformers are rated for 600 VAC 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, 500 kVA Power, 60 Hz Frequency, 3 ph, Lug/Pad Connection, Floor Mounting, 220 deg C Insulation, NEMA 3R Enclosure, 30 to 40 deg C, 0.987 Efficiency, 38 in L x 48-1/2 in W x 59 in H Dimensions

Application

Supplying Appliance, Lighting, Heating, Motorized Machine and Power Loads from Electrical Distribution Systems and Indoor/outdoor applications

Standards

RoHS Compliant | UL File No. E112313 | CSA File No. LR3902 | NEMA ST-20

Features
