Rapid lightning strike protection with extremely short reaction times surge protectors
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.
Product features
1. strict product structure, meticulous and comprehensive protection
2. advanced production process and beautiful appearance
3. self protection voltage is more than self protection, automatic disconnection and recovery.

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.
Brief 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.
Use of attention
1. location is not more than 2000m
2. place should not exceed 50% when the relative humidity is 40.
3. protector is installed with 35MM standard guide rail
