surge arrestors1.CE Certification & Test Report 2.Class D, Lower residual,large discharge current3.Surge protector,SPD
surge arrestors is usually be used in the IT, TT, TN-C, TN-S, TN-C-S and etc power supply system of AC 50/60Hz, rated voltage up to 380V, to protect from direct and indirect lightning impulse and other transient over voltage. As the conditions of IEC61643-1:1998-02 standard, Class II surge protective device, it is category C surge protective device. SPD has two protection modes: MC and MD, SPD is in compliance with GB18802.1/IEC61643-1 standards.
