TDKThe leakage currents under control
In variable-speed drives, the individual components cause leakage currents which, in total, can trigger the residual current circuit breaker and lead to production downtimes. These currents can be largely compensated for with a new type of module.

<p>RCDs (residual current devices) do not differentiate between an actual residual current and a leakage current. If the sum of all system-related leakage currents is too high, the RCD will trip.</p> © TDK
