It is possible to couple the DDA 200 with magnetic-only circuit breakers of the M 200 series, in which case additional thermal type protection must be provided for protection against overload currents.
Type B differential blocks: reliable in any fault situation The detection of fault currents with continuous waveform or high frequency. They were developed for the detection of fault currents with continuous waveform or high frequency.
Types B are suitable in all cases where fault currents with a waveform similar to the continuous waveform or with frequency values and harmonic content such that the correct tripping of types A is not guaranteed, namely, in the presence of:
- Three-phase AC/DC converters where in the absence of double insulation faults may occur in the DC part of the circuit (downstream of the rectifier)
- Three-phase frequency converters where the ground fault current may be high frequency or high harmonic contribution
- Three-phase UPS uninterruptible power supplies where in the absence of double insulation, insulation defects may occur in the DC portion of the circuit (downstream of the rectifier)
- Electromedical equipment where there are devices powered in DC by an AC/DC converter inside the equipment
- Photovoltaic systems without at least a simple separation between the AC side and the DC side.
- Charging stations for electric vehicles with three-phase power supply
