Model 3VTN460
Model 3VTN460 is an assembly of three transformers in one case.
The core and coil assembly is encased in a thermoplastic shell and filled with resin
These transformers are designed for operation line to neutral.
Spacing between live parts per U.L. 1558.
Primary fuses are current limiting, 200kA interrupting capacity, incorporating a rejection feature, typically (class CC ) KTK—R type.
It is desirable to use a 1.6 amp BBS type or equal fuse in the secondary to protect the transformer.
Only ground N/n terminals if source is 3 phase, 4 wire effectively grounded.
See page 7 of this section for a circle diagram for the estimation of the errors for other than rated burdens. See page 27 in this section
for a description of its use.
The transformer has a clear plastic cover.
