The WN-series measuring current transformer detect AC and DC residual currents. The CT can be used in DC, AC, and 3(N)AC systems.
The measuring current transformers feature an integrated metal shield to prevent interferences from external magnetic fields.
The WN series current transformers are suitable for fault current measurement in charging mode 2 (IC-CPD) and charging mode 3 (AC wallbox, AC station). Depending on the requirements of the relevant standards (e.g. IEC 62752, IEC 62955), suitable electronic units (e.g. RCMB104, RDC104 or 6 mA chipsets) are available to complement the transformers.
