Surplus 12 KVA 460/480/500V Wye to 420 Wye 3-phase isolation dry type DTS transformer, N1 rated indoor, UL506 class

Surplus 12 kVA 3-Phase Autotransformer featuring a 460/480/500V Wye primary to 420V Wye secondary configuration. Dry-type construction with N1 indoor rating and UL 506 classification. Ideal for commercial, industrial, and electrical distribution applications requiring reliable three-phase voltage transformation.

Description

Surplus 12 kVA Wye-to-Wye 3-Phase Dry-Type Autotransformer, designed for efficient voltage transformation in commercial, industrial, and electrical distribution applications. These units are predominantly used in industrial machinery environments to interface international machinery with local power grids (European manufacturing equipment) where complete electrical isolation is not mandated by the system architecture.

  • Capacity: 12 kVA
  • Phase: 3-Phase
  • Primary Voltage: 460 / 480 / 500 VAC, Wye
  • Secondary Voltage: 420 VAC, Wye
  • Transformer Type: Autotransformer
  • Enclosure/Installation: N1 rated for indoor applications
  • Standard/Class: UL 506
  • Configuration: Wye-to-Wye
  • Cooling: Dry-type, air-cooled
  • Application:  Industrial and commercial voltage transformation and power distribution

The unit is well suited for applications requiring reliable three-phase voltage reduction from 460/480/500 VAC to 420 VAC. Its dry-type construction provides a low-maintenance alternative to liquid-filled transformers, while the compact autotransformer design can offer an efficient solution where electrical isolation is not required.

Condition: Surplus / excess inventory. Buyers should verify the transformer nameplate, voltage configuration, kVA rating, dimensions, wiring connections, and installation requirements prior to use.
