Open the catalog to page 1

DC sensitive residual current monitoring module for electric vehicle charging systems Product description The residual current monitoring module RDC104-4 is used in combination with a measuring current transformer CTBC17 or W15BS and a type A RCD which has to be provided in the installation for DC fault current monitoring of AC charging systems for electric vehicles in which AC or DC fault currents can occur. The rated voltage Un is 250 V and the rated current (charging current) In = 1 x 48 A/3 x 32 A. The RDC104-4 is suitable for integration into a charging unit Mode 3 (AC) as a RDC-M...
