Eaton 15 kVA 3-Phase 480V to 208Y/120V Transformer
An Eaton 15 kVA 3-Phase 480V to 208Y/120V Transformer is designed to step down three-phase 480-volt power to 208Y/120-volt power for commercial, industrial, manufacturing, lighting, and electrical distribution applications. This voltage configuration is commonly used where equipment requires both 208V three-phase power and 120V single-phase power.
Electrical Supplies Unlimited carries and sources Eaton transformers in a wide range of sizes, voltages, and configurations. We buy and sell new, used, surplus, obsolete, discontinued, and hard-to-find Eaton transformers for electricians, electrical contractors, industrial facilities, businesses, and other customers nationwide.

Used Eaton 15 kVA Transformers
A used Eaton 15 kVA transformer can be an economical solution for a replacement, maintenance project, equipment repair, or industrial application. Used transformers may also be useful when an older Eaton model has been discontinued and a direct replacement is difficult to locate.
ESU buys and sells used Eaton transformers and can help identify equipment based on the manufacturer's nameplate, catalog number, kVA rating, voltage, phase, enclosure, and other specifications. Used electrical equipment should be inspected and evaluated by a qualified electrical professional before installation.
Eaton Transformer Replacement
Replacing a transformer requires more than matching the kVA rating. The primary and secondary voltages, phase, frequency, winding configuration, taps, enclosure, temperature rise, physical dimensions, and installation requirements should all be considered.
If you are replacing an older Eaton 15 kVA 480V transformer, ESU can help locate a current equivalent, used transformer, surplus unit, or discontinued Eaton model. Providing a photograph of the transformer nameplate can help us identify the correct equipment.
Obsolete and Hard-to-Find Eaton Transformers
Eaton has produced many transformer models and configurations over the years, and older models may eventually become discontinued or difficult to source. ESU specializes in locating obsolete Eaton transformers, discontinued transformers, used transformers, surplus transformers, and hard-to-find electrical equipment.
If your normal electrical supplier cannot locate a replacement, contact Electrical Supplies Unlimited. We may have the transformer in inventory or be able to locate one through our network of electrical equipment sources.
