Model 3VTN460
For line-to-neutral connection
• The model 3VTN460 is an assembly of three transformers in one case.
• The primary and secondary terminals are No. 8–32 screws into 1/2” deep brass inserts and
• 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
• It is desirable to use a 1.6 amp BBS type or equal fuse in the secondary to protect
• The transformer has a clear plastic terminal cover.
• Only ground N/n terminals if source is
