RCMP20VC4-03

The RCMP20-03 Series is an AC/DC sensitive residual current monitoring module that monitors ground fault currents, residual currents or leakage currents in single phase or multiple phase installations. The RCMP20-03 Series is suitable for integration into In-Cable Control and Protection Device, according to IEC 62752. Fault Currents in AC and DC may occur in EV charging stations. Mode 2 chargers are devices connected to the electrical grid through an electric socket, which in many older installations may lack an RCD protection. It is required to install RCMP20-03 Series as an AC/DC fault sensor in Mode 2 devices to ensure suitable protection to the end user.

Portable in-cable control and protection device (IC-CPD) is used for Mode 2 electric vehicle charging. The RCMP20-03 Series simultaneously performs the functions of AC/DC residual current detection and opening the protected circuit when the residual current exceeds the specified value, according to IEC 62752. The Mode 2 charging station standard (IEC 62752) requires both AC and DC fault current detection to guard against inadequate protection at the supply IC-ICP connection (i.e., Type A RCD).

The RCMP20-03 Series is monitoring continuously AC and DC residual currents. When failure current exceeds the threshold values the device sends a tripping signal. The module, when coupled with an appropriate switching device, will meet the requirements of an IEC62752 IC-CPD.
