AC/DC-Sensitive Residual Current Protective Device (RCD) With Parameter Configuration

摘要

A residual current protective device (RCD) and a method for AC/DC-sensitive differential current measurement with a voltage-dependent functional unit, which includes an AC/DC-sensitive differential current measuring device, has a current sensor and an AC/DC-sensitive current detection module. A microcontroller configures the voltage-dependent functional unit and evaluates the differential current detected by the AC/DC-sensitive differential current measuring device.
