RCMB104

RCMB104

The AC/DC sensitive residual current monitoring module RCMB104, with patented measurement method, is used in combination with a measuring current transformer W15BS…and a type A RCD which has to be provided in the installation for 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 RCMB104 is suitable for integration into 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 manufacturer of charging systems.
