Model# 468
600V
Low Voltage Potential Transformer
- Terminals are Brass Studs No. 10-32 with one lock washer, flat washer, and nut.
- 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 (58% of rated volts).
- It is desirable to use the proper size fuse in the secondary to protect the P.T. Use a 0.80 amp fuse with Model 468
- With two exceptions these transformers are ANSI C57.13 group 1. Those marked * are group 2.
- Each transformer has two plastic terminal covers.
