Power lightning protection module, primary power protection, 380V protector 1p40KA.

Product introduction

The surge protector is designed according to the standard of IEO and GB. It is applied to power supply protection of equipment system in areas with high lightning risk. It can prevent all kinds of surge currents directly hitting lightning. It can be applied to single-phase and three-phase power supply lines and modular design through different combinations.

Working principle of product

During the operation of the equipment, the lightning arrester will play a protective role once the abnormal voltage occurs.
When the protected device is running under normal working voltage, the arrester will not work, and it will be regarded as a circuit for the ground. Once the high voltage is present and the insulation of the protected equipment is endangered, the lightning arrester acts immediately and leads the high voltage impact current to the earth, thus limiting the amplitude of the voltage and protecting the insulation of the electrical equipment. When the overvoltage is gone, the arrester is restored to its original state quickly, so that the system can supply electricity normally.
The main function of the lightning arrester is to reduce the voltage value of the protected equipment through the action of parallel discharge gap or nonlinear resistance, and to reduce the voltage value of the protected equipment, so as to protect the power equipment.

Notice of product

1. when installing, pay attention to the cable entering and leaving the surge protector. The cables should be separated to avoid the two coupling of surge.

2. grounding lines should be short, thick and straight, so as to reduce the influence of distributed inductors on the ability of lightning electromagnetic pulse.

3. lightning arresters are connected in series between protected equipment

Product features

1. multi-functional overvoltage protection, lightning and overpressure are no longer afraid of disasters.

2. limit the precision of the voltage to say how much!

3. self protection voltage is more than self protection, automatic disconnection and recovery.

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.
