BS EN IEC 62020-1:2021

What is BS EN IEC 62020-1 about?

BS EN IEC 62020-1 applies to residual current monitors for household and similar purposes, having rated operational voltages and a rated voltage of the monitored circuit not exceeding 440V AC rated currents not exceeding 125 A. BS EN IEC 62020-1 applies to monitors performing simultaneously the functions of detection of the residual current, of comparison of the value of this current with the residual operating current of the device and providing the specified warning signal(s) when the residual current exceeds this value. BS EN IEC 62020-1 are intended to monitor the residual current of the installation and to give a warning if the residual current between a live part and an exposed conductive part or earth exceeds a predetermined level.
