Suitable for both indoor and outdoor applications, the MT-PMO-12470D-500KVA-480GRDY.277-N3R provides increased reliablity and protection against critical equipment failures. The lower operating costs, lower heat emissions and lower cost of ownership make this transformer ideal for a wide range of applications and businesses. *PLEASE NOTE: ANY FREE SHIPPING OFFERS DO NOT APPLY TO POWER DISTRIBUTION PANELS, TRANSFORMERS, OR SUBSTATIONS* Transformer Features: With a transformer rating of 500kVA, the MT-PMO-12470D-500KVA-480GRDY.277-N3R transformer is a three phase unit with a primary voltage of 12470V Delta. It also provides a secondary voltage of 480GRDY/277 Grounded Wye. Featuring robust construction, this unit`s cores are manufactured with non-aging, cold-rolled silicon steel laminations using state of the art technology. The MT-PMO-12470D-500KVA-480GRDY.277-N3R is a grounded wye connection transformer and therefore must be connected phase-to-ground on a grounded wye system. This unit boasts a low cost of ownership and is highly energy efficient. Lower heat emissions mean less cooling is needed as well. The Standard NEMA Type 3R enclosure makes the unit suitable for both indoor and outdoor applications and it can be pad mounted. The unit also features mineral oil cooling and a 65¡C temperature rise and is rated IP24. The MT-PMO-12470D-500KVA-480GRDY.277-N3R is designed so that no excess oil heating occurs from unbalanced loads or phase loss on the primary side. Benefits: The MT-PMO-12470D-500KVA-480GRDY.277-N3R pad mount dead front loop feed transformer offers many benefits to the consumer. Precision cut copper transformer winding material help to improve performance. The close tolerances used during manufacturing also eliminates burrs which hinder performance. Each core is specially coated to prevent the ingress of moisture and are electrically balanced to minimize axial forces during short circuit situations. This transformer provides owners with significant energy savings as well as offering environmental benefits. Higher efficiency not only extends the life of the transformer, but also turn into cost savings for owners in the form of lower energy bills and decreased cost of ownership. Applications: General purposes. Larson Electronics is a manufacturer and as such can build stationary and portable transformer systems to your specifications. Although we carry several models of power distribution transformer systems, we can deliver custom ordered units almost as quickly as our prebuilt units.
