VT Pack™ 4:1 ratio 12.5 VA

This fully ANSI compliant VT Pack™ with a ratio of 4:1 is designed to be used on 480V 2-wire single phase and 480/240 3-wire single phase applications. The “A” designation specifies 12.5 VA rating. This VT Pack consists of one revenue-accurate voltage transformer that is encased in epoxy inside a UV-resistant polycarbonate enclosure. 

This VT Pack can be used with induction (disk type), solid-state fixed voltage, or a Form 3S or 4S class 20 solid state-wide voltage range meter. The connector on the VT Pack mates with a wiring harness or the wiring harness in one of our sockets. For conventional transformer-rated applications, a color-coded wiring harness is available with either our standard 6-foot harness or custom wire 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. 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.
