Model# 456 600V
Low Voltage Potential Transformer
- The primary and secondary terminals are No. 10-32 screws into 3/8ā³ deep brass inserts and fitted with one lock washer and one flat washer and are contained in a sealable terminal cover.
- The core and coil assembly is encased in a thermoplastic shell and filled with resin.
- These transformers are designed for operation lineto- line. They may also be operated line-to-ground or line-to-neutral, at reduced voltage, (58% of rated volts).
- It is desirable to use a 5.0 amp BBS type fuse in the secondary to protect the transformer.
- With six exceptions these transformers are ANSI C57.13 group 1. Those marked * are group 2.
- IEC Rated models are available.
- Fuse blocks containing type KTK-R (class CC) fuses can be fitted.
- When primary fuses are requested, the ratings will be as given in the table.
- This page contains a circle diagram for the estimation of the errors for other than rated burdens.
- When only one fuse is used, it must be connected into the line side (H1) terminal wiring. This will prevent the presence of voltage at the H1 terminal for a ruptured fuse in the neutral (H2) terminal wiring for line-to-neutral connected transformers.
