单、三相交流电源防雷箱

单、三相交流电源防雷箱适用于B、C、D级过电压保护，主要安装在室内低压配电柜（箱）处，当电源线路产生操作过电压或雷击的过电压时，防雷箱能立即在纳秒级的时间内迅速导通，将过电压的幅值限制在设备的安全工作范围内，同时将过电压的能量泄入在地。
LYD2-F series single-phase and three-phase lightning-proof box is suitable for B,C,D grade over-voltage protection,mainly installed in household low-voltage distribution box,when the power supply system shocked by over-voltage or lightning, or lightning,it'll rrpidly transmit in ns and limit the over-voltage in safe range and protect the electric equipment,simultaneity discharge the surge into earth.
