RCMB104
The AC/DC sensitive residual currentmonitoring module RCMB104, with patented measurement method, is used incombination with a measuring current transformer CTBC17 and a type A RCD which has to be provided in the installation forfault current monitoring of AC charging systems for electric vehiclesin which AC or DC fault currents can occur.The rated voltage Un is 250 V and the rated current (charging current) In = 1x48 A / 3x32 A. The RCMB104 is suitable for integrationinto a charging unit (IC-CPD, wall box) according toIEC 61851-22, IEC 62752 and UL 2231-2.
The RCMB104 is only intended for purchase by the manufacturerof the charging system and not for end users!
