All-pole sensitive residual-current monitoring unit (RCMU)/DI converter
Complying with the relevant norms, electrical devices must be disconnected from the power distribution grid at the latest in the event of a residual current of 30 mA.
Our transformerless inverters are therefore equipped with all-pole sensitive residual-current monitoring units (RCMU), which can measure the differential current (leakage current + residual current).
You will find additional information in the technical information sheets “Leakage Current” and “Criteria for Selecting a Residual-Current Device (…)”.
They are available in our homepage’s download area at:
