• Terminals are brass studs No. 10–32 with one lockwasher, flatwasher and regular nut.
• These transformers are designed for operation line-to-line. They may also be operated
• It is desirable to use a 0.80 amp fuse in the secondary to protect the transformer.
• With two exceptions these transformers are ANSI C57.13 group 1.
• Models 468–380, 468-400, 468–416 designed specifically for 50Hz operation are available
• Each transformer has two plastic terminal covers.
• The core and coil assembly is encased in a thermoplastic shell and filled with resin.
• Approximate weight: 4 lbs
line-to-ground or line-to-neutral at reduced voltage, (58% of rated volts).
Those marked * are group 2.
