The DA6300V Delta 300KVA transformer is designed for efficient operation at 600-120/208V, featuring a NEMA 3R enclosure for durability in outdoor applications. Ideal for various industrial settings, this transformer ensures reliable power distribution while safeguarding against environmental factors. A perfect choice for enhancing your electrical system’s performance and safety.
The DA6300V steps down from a 600V primary to a 120/208V three-phase, four-wire (wye) secondary. This output is the standard voltage for feeding 120/208V distribution panelboards, powering both 120V single-phase branch circuits and 208V single-phase or three-phase loads — common in Canadian commercial and industrial installations.
Yes. The NEMA 3R enclosure rating means the transformer is designed to withstand falling rain, sleet, and the formation of ice on the enclosure without affecting safe operation. It is suitable for outdoor installations such as rooftops, covered dock areas, or exterior building walls, provided it is not subject to direct submersion or wash-down conditions.
