Product introductionOmldeen surge protection device, SPD (also known as lightning arrester, lightning arrester, surge protector, overvoltage protector), with high lightning current capacity, is suitable for electromagnetic pulse (EMP) protection of TN-S, TN-C-S, TT, it and other power supply systems with AC 380V (50 Hz / 60Hz) and below. It is used at the junction of lpzoa or lpzb area and lpz1 area
Working principleSurge protective device (SPD) is an indispensable device in the lightning protection of electronic equipment. Its working principle is that under normal conditions, the SPD is in a high resistance state, so as to ensure the normal operation of the power supply system; when the surge overvoltage and over-current appear on the system line, the resistance of SPD changes suddenly or continuously drops to low impedance, and SPD will conduct in nanosecond level immediately After the surge, the surge protection device will return to the high resistance state quickly, which will not affect the normal power supply of the system.
Features1. Stable and reliable performance, suitable for different grid systems, more comprehensive protection, ns level response speed.
2. It can withstand 25kA (10 / 350 μ s) lightning current impact.
3. Flame retardant shell design, can be easily installed on 35mm electrical guide rail.
4. Energy saving, environmental protection, easy installation, no special maintenance.
The product should be used in the installation positionOmldeen class I series surge protective devices are suitable for lpzoa area or interface between lpzob area and lpz1 area in lightning stroke area. They are usually installed in parallel at the main distribution cabinet at the low-voltage household end of buried through pipe incoming line or floor distribution cabinet.
Typical applications: mobile communication base station, microwave communication bureau / station, telecommunication room, industrial factories and mines, civil aviation, finance, securities and other power systems, such as various power distribution stations, distribution rooms, distribution cabinets, switch boxes and other important and lightning prone equipment.

1. The SPD should be installed in parallel. Generally, only one of the two terminals can be connected, or double connection mode (Kevin connection mode) can be used. The connecting wire shall be firm and reliable, and shall be short, thick and straight.
2. When installing, please connect according to the installation diagram, where L1, L2 and L3 are phase lines, n is zero line, PE is ground wire, do not connect wrongly. After installation, close the automatic circuit breaker (fuse) switch.
3. It is recommended to connect fuses or automatic circuit breakers in series at the front end of SPD. Ensure to avoid fire caused by short circuit after deterioration of lightning arrester.
4. Remember that live working is not allowed. Power supply must be cut off before installation. Live working is strictly prohibited.
5. Grounding must be good and meet the requirements of relevant national lightning protection specifications
6. The equipment needs regular inspection and must be replaced immediately after deterioration.
