Lightning protector 20ka ~ 40ka voltage 220V AC surge protector

Product introduction

Surge protector is mainly used to protect the lines from lightning and over voltage protection. The circuit protection is made up of a powerful diode solid state discharge tube; basic and fine protection is based on automatic fault protection device technology. In thermal overload, the device moves the two ends of the original lightning protection together, thus causing the damage of the surge.

Product specification

Product Installation

With 35mm standard DIN-rail mounting, connecting copper stranded conductor is 2.5~35mm²

At front of spd each pole must be setted protection---used fuse or miniature circuit breaker lightning current SPD protection,after SPD breakdown to short circuit protection.

SPD install on protected line(equipment) to the front and connected to the supply line. A class products install in the building home-entry line hold larger surge current total distribution box. B, C class products most install on the floor distribution box, D class products close to the front-end equipment that smaller surge current, smaller residual voltage place.

Working principle of product

Surge protector is an indispensable device in lightning protection of electronic equipment. It used to be called "lightning arrester" or "overvoltage protector". The function of surge protector is to limit the transient overvoltage to the power line and signal transmission line within the electric pressure range that the equipment or system can bear, or to inflow the powerful lightning discharge into the ground. The protected equipment or system is not damaged by impact.

Use of attention

1. lightning arrester must be reliably connected to the ground wire of the lightning protection system, and the connection line is short, thick and straight.

2. ambient air temperature is no more than +40 C and no less than -5 C, and the average value of 24 hours is no more than +35 C.

3. the relative humidity of the installation site is not more than 50% when the relative humidity of the air is 40.

Product features

1. installation and use of convenient novice can also be easy to install

2. core components are strictly screened, stable performance and reliable operation.

3. the product has many interfaces and is easy to use. It doesn't need to worry about the number of interfaces.
