Model 475
- The core and coil assembly is encased in a thermoplastic shell and filled with resin.
- These transformers are designed for operation line-to-line. They may also be operated line-to-ground or line-to-neutral at reduced voltage voltage, (58 % of rated volts).
- It is desirable to use a 3.0 amp BBS type or equal fuse in the secondary to protect the transformer.
- Model 475 transformers are ANSI C57.13 group 1, except for 475-480 and 475-600 which are group 2.
- Transformer has a clear plastic cover.
