2015 cngz 5kA 15kA 20kA ac lightning surge protector

     hot sale 4P SPD 380V 10KA/20KA surge protection device 

The products comply with IEC61643-1, GB18802.1.

The housing is fixed on 35mm electrical guide, and with failure release device inside. As long as SPD become invalid after the breakdown caused by over-heat and overload current, the failure release device will be disengaged from power system automatically with the warning indicator turning from Green (normal) to Red (failure).

SPD is usually installed in household power distribution boards, telecom machinery center, computer equipment center, elevator control center, hospital's surgery and ICU, information equipment, electronic equipment and in front of control equipment or nearest socket box of control equipment.
