该电路持续监测电流波形。对于AFCI：分析电流特征以区分正常操作电弧（例如来自开关）和危险的串联或并联电弧故障。对于GFCI：比较火线和零线中的电流；任何不平衡（通常>4-6mA）表示接地泄漏。检测到故障后，固态或机电脱扣机构在毫秒内打开断路器触点以中断电源。

不是客户评论，也不是实时热度。以下维度用于前期 RFQ 准备和供应商评估。
这些分值是采购评估维度示例，不代表真实客户评分、具体国家买家反馈或实时询盘。
AFCI (Arc Fault Circuit Interrupter) detects dangerous electrical arcs that can cause fires, while GFCI (Ground Fault Circuit Interrupter) detects ground faults that can cause electric shocks. This combined circuit provides both types of protection in one unit.
The circuit uses copper conductors for optimal conductivity, ferromagnetic cores for efficient current sensing, semiconductor sensors like Hall-effect sensors for precise fault detection, and polymer/thermoset plastic housing for electrical insulation and mechanical durability.
When the signal processor detects an arc fault or ground fault through the current sensor, it triggers the trip mechanism which physically interrupts the electrical circuit within milliseconds, cutting off power to prevent fire or shock hazards.
