The ACT-633 / 645 indoor, auxiliary current transformer is a 600 volt rated unit for use in secondary circuits. This unit is used to change the effective current ratio for operating watt-hour meters, relays, and other control and metering devices and for secondary circuit isolation. Due to superior saturation characteristics, these transformers generally do not saturate under extreme high fault currents.
The ACT-983 indoor/outdoor auxiliary current transformer is a 600 volt rated unit for use in secondary circuits. The unit can be provided with 10 kV BIL for use in primary circuits. This dry-type, solid-cast current transformer will operate with high accuracy for metering or relay applications. The unit is best suited for use in changing the effective current ratio for operating watt-hour meters, relays, and other control and metering devices needing revenue metering accuracy. Due to superior saturation characteristics, these transformers generally do not saturate under extreme high fault currents.
