Modern Residual Current Protection

In contrast to type A RCCBs, the new type F RCCBs from Doepke not only detect alternating residual currents and pulsating direct residual currents corresponding to the mains frequency, but also residual currents consisting of mixed frequencies.

As a result of the increased use of electronic equipment in private households, residual currents may occur which cannot be reliably detected by type A residual current circuit-breakers. The reason for this is that single-phase operated frequency converters are increasingly being used to control the speed. In the event of faults, these frequency converters can generate residual currents with mixed frequencies other than 50 Hz.
