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);
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.
