A60030125 2.4:1 12.5 VA
VT Pack
This VT Pack™ is for 480/277 4-wire wye applications where traditional 2.4:1 VTs are used. For all other 480V applications, we recommend other versions—see catalog for various options.

This VT Pack consists of three revenue-accuracy toroidal voltage transformers for use with modern wide voltage range electronic watthour meters or older induction (disk-type) meters. The transformers are encased in epoxy inside a UV-resistant polycarbonate enclosure.

This VT Pack can be used with either standard transformer-rated meters or the Form 9S, Class 200 solid state polyphase meter The connector on the VT Pack mates with a wiring harness, or the wiring harness in one 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, or other convenient location. 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.
