Technical informations

MRCDs detect and evaluate residual currents in terms of its level and duration. If the limit value is exceeded, they trigger the disconnection of the affected system part via an external switch-off device. Modular residual current devices (MRCD) are used to protect against residual currents, if residual current circuit-breakers cannot be used due to the high load currents or mains voltages.
