The XTDB019 is a residual direct current monitoring module (RDC-M-module) which, electrically coupled to a protection unit or switching unit, performs the function of the residual direct current monitoring device (RDC-MD), in full compliance with the requirements of IEC 62955. As an option, the module can also integrate residual alternate current monitoring, in compliance with the threshold and timing requirements for RDC-PD devices.
The module is suitable for use in AC charging stations permanently connected to the mains (mode 3 according to IEC 61851-1), where is prescribed the presence of a residual direct current detecting device (RDC-DD) with 6mAdc trip threshold.
The XTDB019 features a wide cable passage (19 mm) and is available with optional UART communication.
