RDC104-4
The residual current monitoring module RDC104-4 is used in combination with a measuring current transformer 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 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!

- Three outputs (DC1, DC2, Error)
- Patented measurement method (Patents: EP 2 571 128 / US 9,397,494 / ZL 201210157968.6 / CN 103001175, EP 2 813 856)
- Measuring range DC ±300 mA
- Residual current resolution 0.2 mA
- Load current up to 48 A r.m.s. (single-phase) or 3 x 32 A r.m.s. (three-phase)
- Fault output (integrated self monitoring and test functions)
- High insensitivity to external interferences
- Wide range of use even in severe environments (e.g. in the event of external magnetic fields)
- As a RDC-M module in applications according to DIN EN 61851 or IEC 62955, the RCD104-4 can replace a type B RCD when combined with a type A RCD and a suitable switching device (e.g. a power relay).
