Installation
◆ Installed at the junction of LPZ1 or LPZ2 zone and LPZ3 zone using 35mm standard quide rails,connecting copper stranded wires with 2.5~16mm².
◆Each pole of SPD must be protected-use fuses or miniature circuit breakers or special backup protectors.
◆Suitable for household distribution boxes,computer equipment,and information equipment. In front of or nearest socket box of electronic equipment and control equlipment

Main structure and working principle
◆ SPD is a port, anti-shock protection, indoor fixed installation, voltage limited type.
◆ SPD has a built-in disconnector. When the SPD falls due to overheating or breakdown, the disconnector can automatically disconnect it from the power grid and give an indication signal at the same time.
◆The visible window displays green when the SPD is working normally, and displays red when it fails to disengage.
◆1P+N,2P+N,3P+N are composed of 1P,2P,3P SPD+NPEzero-ground protection modules, which are used in TT,TN-S and other power supply systems.
