CKDL4 Type B Residual Current Operated Circuit Breaker (RCCB)
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. Conform to the standard: GB16916.1 IEC / EN61008-1, GB / T2279, IEC / EN62423 1. lt can protect complex waveforms such as compound wace, two-phase or three-phase rectifier wave and smooth DC wave. 2. Suitable for photovoltaic power generation, frequency converter, charging pile and other occasions with large dc component.
