IDU-20kA/1P,2P,3P,4P surge protector
Company Brand：Yidun
Product Description：IDU-20kA/1P, 2P, 3P, 4P surge protector (hereinafter referred to as SPD) is used in IT, TT, TN-C, TN-S, TN-C-S and other power supply systems of low-voltage AC distribution systems to protect against indirect lightning and direct lightning effects or other transient overvoltage surges into the SPD, which has common mode (MC) and differential mode (MD) protection modes. GB/T18802.1/IEC61643-Ⅱ.
Overview
IDU-20kA/1P, 2P, 3P, 4P surge protector (hereinafter referred to as SPD) is used in IT, TT, TN-C, TN-S, TN-C-S and other power supply systems of low-voltage AC distribution systems to protect against indirect and direct lightning effects or other transient overvoltage surges. GB/T18802.1/IEC61643-Ⅱ.
Installation
◆Install on standard 35mm rail at the junction of LPZ1 or LPZ2 and LPZ3, and connect 2.5~16mm² multistrand wires.
◆Each pole of the SPD must be protected by a fuse or a small circuit breaker or a special back-up protector.
◆Applicable to household distribution boxes, computer equipment, and information equipment. In front of electrical equipment and control equipment or in the nearest outlet box.
Main structure and working principle
◆SPD is a outlet, anti-shock protection, indoor type fixed installation, voltage limiting type.
◆SPD has a built-in disconnector. When the SPD fails due to overheating or breakdown, the disconnector can automatically disconnect it from the electric grid and give a signal at the same time.
◆The 1P+N, 2P+N, 3P+N is composed of 1P, 2P, and 3P SPD + NPE zero-ground protection modules, and should be used in TT, TN-S, and other power supply systems.
