The best power supply lightning protector , 40KA power supply lightning protection

Product introduction

The surge protector is suitable for power supply systems such as 50/60Hz 380V and below N-S, NT-C, TH-C, TT and LT. It can be used as the equipotential connection at the interface of LPZ1, LPZ2 and LPZ3. The design is based on IEC61643-1 and GB18802.1. The shell is mounted on the 35mm electric guide. The product has built-in failure detaching device. When the surge protector overheat and breakdown, the failure exfoliation device can automatically remove it from the power grid, and the alarm indicator module is turned from white (normal) to red (fault).

Notice of product

1. data line: more than 2.5mm2; when the length of more than 0.5 meters of more than 4mm2

2. the standard RJ45 interface can be conveniently connected to the front end of the protected equipment. The grounding path should be as short as possible, and the length should not exceed 1.5 meters.

3. when installing, pay attention to cables coming in and out of surge protective devices, so as to avoid the two coupling of surge.

4. the protected equipment must have good grounding, and the grounding impedance value is according to the relevant standard.

Working principle of product

Surge protector not only can be used to protect the high voltage of the atmosphere, but also to protect the operation of high voltage. If there is a thunderstorm, a high voltage will appear and the electric equipment may be dangerous. At this point, the arrester will play a role to protect the power equipment from damage. The most important function of the arrester is to limit the overvoltage to protect the electrical equipment. Lightning arrester is a device to make the lightning current flow into the earth, so that the electrical equipment does not generate high voltage.
