Oule Class III Surge Protection Device (SPD) (also known as Lightning arrester , lightning arrester, surge protector, overvoltage protector), applicable to lightning electromagnetic pulse (LEMP) protection generated by lightning strikes in power supply systems such as TN-S, TN-C-S, TT, IT, etc. with AC 380V (50Hz/60Hz) and below, used for LPZ 2-3 area or higher interface in lightning strike area, and its design basis shall comply with GB18802.1, IEC61643-1 technical standard is used for the third level fine surge protection at the equipment end.

Operating principle of surge protector:

Surge protective device (SPD) is an indispensable device in the lightning protection of electronic equipment. Its principle is that under normal conditions, the SPD is in a high resistance state to ensure Power Supply The system works normally; When surge over-voltage and over-current occur on the system line, the resistance of SPD suddenly changes or continuously decreases to low impedance, SPD immediately turns on in nanosecond time, and discharges surge energy into the ground through SPD; When the surge is over, the surge protector will quickly return to the high resistance state, which will not affect the normal power supply of the system.

Functional features of surge protector:

1. The optional remote communication terminal can start the emergency signal function to facilitate remote start of emergency signal monitoring.

2. It can withstand 20KA (8/20 μ s) lightning current impact.

3. The response speed is fast, and the action response time is less than 25ns.

4. The flame-retardant shell design can be easily installed on the 35mm electrical guide rail.

5. Built in thermal tripping failure disconnection device enables the lightning arrester to automatically disconnect when it fails due to overheating and breakdown.

6. Visual alarm window The color of the port indicates the working status of the protection, green (normal), red (fault).

Application and installation location of surge protector:

Oule III series surge protector is applicable to LPZ2-3 area or higher interface in lightning strike area, generally used for fine overvoltage protection of electronic equipment to prevent terminal equipment from overvoltage interference. It is a Class III (D) overvoltage protector; Usually installed in households Power Distribution Box , in front of computer center, information equipment, electronic equipment and control equipment, or Socket Box.
