Voltage surge protectors
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 III 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.
Working principle
SPD have only one side terminal, able to prevent from being electric touching, indoor fixedly mounted, limiting voltage.
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 net work. it will show red color.
1P+N,2P+N,3P+N SPD consist of 1P,2P,3P SPD and NPE neutral and earthing protection modules, used in the power supply system of TN-S,TN-C-S and etc.
