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).
FREQUENCY: 60 Hz
STANDARD SECONDARY VOLTAGE: 120V
INSULATION LEVEL: 600V, 10kV BIL full wave
ACCURACY CLASS: ± 0.6% at all burdens up to 7.5VA and ±1.5% sy 20VA burden
THERMAL RATING: 75VA at 30°C amb., 50VA at 55°C amb.
- The transformers are encased in a thermoplastic case with the core and windings encapsulated in resin.
- Terminals are No. 10-32 brass studs with one lock washer and one flat washer each.
- Note: All transformers listed with the exception of the 480v and 600v are ANSIC57.13 group 1. The 480v and 600v are group 2.
- It is desirable to use a 0.8 amp fuse in the secondary to protect the transformer.
