The next generation from KEDU, the B Type CKDL4 products are now available. Leakage breaker protection developed specifically for photovoltaic power generation, inverter, charging station and other high-end markets with large DC component. It has four advantages: stability and reliability, accurate selection, time/labor-saving, and more accurate leakage protection.

Applicable Scope

CKDL4 series residual current circuit breaker is applied to the lines with rated voltage of 400V~(3P+N), and rated current of 63A. In case of electric shock or electric leakage current exceeds the specified value, the residual current circuit breaker can switch off the fault circuit in a very short time, protecting the safety of person and electric equipment and conforms to the standard: GB 16916.1 IEC/EN 61008-1, GB/T 22794, IEC/EN 62423

Type B: Provides protection for sine AC residual current with 1000Hz and below, DC pulsating residential current, compound residential current and smooth DC residential current, with high trip resistance. lt can protect complex waveforms such as compound wave, two-phase or three-phase rectifier wave and smooth DC wave. Suitable for photovoltaic power generation, frequency converter, charging pile and other occasions with large dc component.
