RDC104-4
The residual current monitoring module RDC104-4, with patented measurement method, is used in combination with a measuring current transformer CTBC17 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 module according to IEC 62955.
The RDC104-4 is only intended for purchase by the manufacturer of the charging system and not for end users!
