Description

Used 15 KVA 600Y V to 480Y V 3-Phase Auto Dry-Type Transformer – Indoor Rated

This is a professionally maintained used 15 KVA auto dry-type transformer, designed for indoor applications. It is configured for 600Y V primary to 480Y V secondary, operating on a 3-phase, 60 Hz system. As an auto transformer, it offers a compact and cost-effective solution for voltage step-down within close voltage ratios.

Specifications:

  • Power Rating: 15 KVA

  • Primary Voltage: 600Y V

  • Secondary Voltage: 480Y V

  • Configuration: 3-Phase, Wye-Wye (Y-Y)

  • Type: Auto Transformer, Dry-Type

  • Cooling: Natural air-cooled (ventilated)

  • Enclosure: Indoor (typically NEMA 1)

  • Frequency: 60 Hz

  • Mounting: Floor or wall mount (depending on design)

Features:

  • Space-saving design with fewer windings than isolation transformers

  • Suitable for indoor environments with proper ventilation

  • Ideal for industrial, commercial, or facility retrofits requiring voltage conversion between 600V and 480V systems

  • Tested and inspected for functionality prior to resale

Condition:

  • Used – good working condition

  • Inspected for electrical integrity and mechanical stability

  • Minor cosmetic wear consistent with previous indoor installation

Applications:

  • Power distribution adjustments in commercial or industrial facilities

  • Equipment compatibility for voltage-specific machines

  • Cost-effective retrofit solutions in existing 600V systems requiring 480V loads
