Product Features:
combination type SPD
The smallest size single phase surge protector of Iimp: 20KA ;
only 27mm width, save space;
Sealed metal air gap technology,high energy electronic trigger discharge gap, with the ability to block continuous flow
Low output residual;
fast response time (≤25ns);
◆ 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.

The combination type SPD characteristics:
HDU1-II20X series Surge protector device (hereinafter referred to as SPD) is used for power supply systems such as IT, TT, TN-C, TN-S,TN-CS, etc. for low-voltage AC distribution systems, for indirect lightning and direct lightning or other A surge of transient overvoltage is protected. The SPD has a common mode (MC)and differential mode (MD) protection. The SPD complies with GB/T18802.1/EC61643-Il.
