The Square D EXN150T3H is a three-phase low voltage dry type distribution transformer that complies with DOE energy conservation standards and NRCan minimum energy efficiency levels. This 150kVA transformer features a 480V primary and 208Y/120V secondary with aluminum windings and a 220 insulation system designed for a 150 degree C temperature rise.
Complies with DOE energy conservation standards and Natural Resources Canada (NRCan) minimum energy efficiency levels.
Terminals accommodate wire ranges sized for 125% of the secondary nameplate current and 250% of the primary nameplate current.
Shipped as Type 2 for indoor installation, field convertible to Type 3R via weathershield for outdoor installation.
Product Highlights
This Square D transformer is air-cooled, floor mounted, and designed to function with other Square D equipment. It has a low sound level, and its inrush is coordinated to meet identified breaker trip curves.
