- 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).
- Terminals are brass studs No. 10-32 with one lockwasher, flatwasher, and regular nut.
- 460-480 and 460-600 are ANSI C57.13 Group 2.
- 480V for 480V Wye, 4:1 turns ratio
- 600V for 600V Wye, 5:1 turns ratio
- All others are ANSI C57.13 Group 1.
- 120V for 208V Wye, 1:1 turns ratio
- 240V for 416V Wye, 2:1 turns ratio
- 300V for 520V Wye, 2.5:1 turns ratio
- It is desirable to use a 1.6 amp fuse in the secondary to protect the transformer.
- Models designed specifically for 50 Hz operation (468 are available with reduced performance.
- Each transformer has two plastic terminal covers.
- Approximate weight: 7.75 lbs
