DIN EN 50630 VDE 0667-10:2014-11

This European Standard applies to Main Residual Current Protection devices operating with time Delay on residual current detection, not incorporating overcurrent protection (hereafter referred to as MRCP-D), for rated voltages not exceeding 440 V a.c. and rated currents from 40A and not exceeding 125 A for fixed installations. MRCP-DThese devices are intended to provide automatic disconnection of supply (fault protection) in case of a fault in the distribution circuit and in final circuits exceeding 32 A, according to HD 60364-4-41clause 411.3.2.3 and 411.3.2.4. They may be used to provide protection against fire hazards due to a persistent earth fault current, without the operation of the overcurrent protective device. They may provide selectivity against RCCBs of type S and general type.
