Product introduction
LYD1-B series surge protective device is suitable used in the IT, TT, TN-S, TN-C-S and low-voltage AC power distribution system, rated voltage up to 380V, to protect from direct and indirect lightning impulse and other transient over voltage. As per the conditions of IEC61643-1:1998-02 ST standard, Class 2 surge protective device, it is category B surge protective device. SPD has two protection modes: MC and MD, SPD is incompliance with IEC 61643-1 standards.
Operation Elements
In three phase and four wires system, all three lines and one neutral line to earthing line have SPD to be protected, in normal service, the SPD is at the state of high resistance, when network produce surging over-voltage due to thunder or other reasons, SPD will be conductive within short tines(ns), lead surging voltage into ground, consequently to protect the electric appliances of network. After surging voltage passed by SPD, and disappeared, SPD recover in high resistance. It will not have influence on the normal service of network.
Installation
- The SPD need not to be adjusted after in-stalled according to requirement.
- It can automatically protect the power network after proper installation.
- SPD is invalid or not, meanwhile check red indicator of fuse lightning or not, please replace the invalid element on time.
