The ZCT406 is a customizable Zero Phase Current Transformer rated at 400A DC with 70±3Ω resistance and can withstand 2500Vrms. It operates on the principle of Kirchhoff’s current law to provide ground fault protection, with no secondary output during normal conditions and activating during faults to trip the power supply.
