защиты от перенапряжений SPD устройства (с NPE)

We are professional surgeprotectormanufacturer,our surgeprotectorbased on IEC61643-1 ,and GB18802.1 standard design for ABC -level surge protection for lightning over-voltage generated when the surge protection(SPD) . Power surgeprotectorinclude modular single-phase power surge protector,modular three-phase power surge protective device,mine box-type three-phase power surge protector,three-phase AC power supply integrated lightning protection module,fine power surgeprotectorand home surge protector,lightning power surge protective device sockets. The characteristics of this type power surgeprotectorare: 1. Big Imax and small volume 2.Adopt temperature control circuit protection technologies,it has quick response time. 3. The residual voltage of this sugeprotective deviceis down ,leakage current is small. 4. Functional modes indication: green light stands for normal operation, while red light stands for breakdown. The remote signalling monitoring interface adopted can achieve remote monitoring 5.This typesurge protective device(SPD)is suitable for various harsh environments. It is easy to install and maintenance-free; its overall protection conforms to international standards and is certified by Chinese certification authorities.
