AFDD Fault Arc Circuit Breaker

AFDD Fault Arc Circuit Breaker (JCAFCI-0-S1-D63)   Suzhou Jiangchao Electrical Technology Co., Ltd. is proud to introduce the Proactive Arc Fault Detection Circuit Breaker, a state-of-the-art device that combines advanced arc fault recognition with reliable overcurrent and leakage protection. This unit is designed to detect dangerous series and parallel arc faults—the primary cause of electrical fires—and interrupt the circuit within milliseconds, preventing ignition from frayed cables, loose connections, or aged insulation. Its intelligent algorithm distinguishes between hazardous arcs and normal operational sparks (such as those from motor brushes or switching transients), effectively eliminating nuisance tripping and ensuring uninterrupted power supply for critical loads. Rated for single‑phase AC230V systems with current ratings from 6A to 63A and a short‑circuit breaking capacity of 4.5kA, it integrates a default 30mA residual current protection, offering comprehensive safety in…
