Summary:
This unit is designed to protect a standard 120/208VAC 3-phase WYE configurations (center grounded), AC power feeder. This unit will protect in all modes. That is,
differential protection Phase-to-Phase and also each Phase-to-Ground. This is a primary stage protector and would be connected at the Breaker /
Distribution Panel before the power is distributed throughout the Signal House or Case.
