Technical Parameter

Operation Elements
In three phases and four wires system, all three phase 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 time (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 net-work after proper installation.
– On services it need periodically check if SPD is invalid or not, meanwhile check red indicator of fuse lighting or not, please replace the invalid element on time.
