Voltage surge protective device
LY series surge protective device (SPD) 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 I surge protective device, it is category B surge protective device. SPD has two protection modes: MC and MD, SPD is in compliance with GB18802.1/IEC61643-1 standards.
Working principle
1.SPD as only one side of terminals, able to prevent from being electric touching, indoor
fixedly mounted, limiting voltage.
2.SPD has built-in disconnector, when SPD is invalid due to overheating or breakdown, the disconnector can automatically separate SPD from the network, meanwhile send an
indication signal. The visible window show white color in normal service, if to be separated
from network, it will show red color.
3.Max discharging current of each wire: up to 100KA.
