VT Pack™ A6003012

Compatibility Features

  • Phase

    • 3-Phase 4-Wire Wye
  • Ratio

    • 2.5:1 ratio 12.5 VA

This VT Pack™ is for 480/277 volt 4-wire wye applications where traditional 2.5:1 VTs are used. For all other 480V applications, we recommend other VT Pack versions or products. Please refer to the “Products” tab including “Which VT” and or the “Education” tab for product literature.

The “A” designation specifies 12.5 VA rating. This VT Pack consists of three revenue-accuracy toroidal voltage transformers for use with solid state wide voltage range electronic watthour meters or older induction (disk-type) meters. The transformers are encased in epoxy inside a UV-resistant polycarbonate enclosure.

The connector on the VT Pack mates with the wiring harness of our sockets or block assemblies. For existing transformer-rated applications, a color-coded wiring harness is available either with our standard color code or can be supplied in custom color-coding and lengths to meet your Company's requirements.

The VT Pack can be mounted in a pad mount transformer, transformer cabinet, on the outside of an existing meter socket, in one of our enclosures designed for that purpose ( refer to “Product” page, “Enclosure” tab, Long Narrow or Universal ), or other convenient location. The “A” designation specifies 12.5 VA rating. Many meter socket manufacturers offer “extended” sealed compartments to accommodate a VT Pack isolating the 480 volts. The keyhole slot on the VT Pack makes mounting on any 1/4" mounting screw or shoulder rivet quick and easy. The VT Pack can also be mounted on a cross arm, pole or other suitable outdoor location when used with the optional Connector Cover.


A REQUIRED harness is used for external mounting of the VT Pack™ in transformer-rated applications and is available in our standard 6-foot, 12-foot, or 20-foot lengths and color code.

The harness can also be customized to any length and color code to accommodate your company's requirements.
