RCMB104

The AC/DC sensitive residual currentmonitoring module RCMB104, 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 forfault current monitoring of AC charging systems for electric vehicles in which AC or DC fault currents can occur.

The module is, depending on the variant, suitable for integration into a charging unit (Mode 2, IC-CPD,) according to IEC 62752 or UL 2231-2 (CCID5 or CCID20).

The RCMB104 is only intended for purchase by the manufacturerof the charging system and not for end users!
