385V 20ka ~ 40ka Type2 surge protective device Power Systems
Brief introduction
Surge protector is used to protect the line from damage caused by lightning induced voltage, power interference, electrostatic discharge and so on. The surge protector uses a multilevel protection circuit, selects the brand components, and makes use of advanced production technology. It has the characteristics of low flow residual pressure, sensitive reaction, stable performance, reliable work and so on. It is suitable for family housing, the third industry and industry.
Working principle of product
The function of surge protector is to limit the transient overvoltage to the power line, the signal transmission line in the voltage range that the equipment or system can bear, or to inflow the powerful lightning discharge into the ground, and protect the protected equipment or system from damage by the impact.

Product features
1. cut off the line when undervoltage occurs, and reset automatically after restoration.
2. copper fittings have good electrical conductivity
3. new technology, high energy, gap discharge electrode N-PE.
4. use temperature control protection circuit, built-in thermal protection
Notice of product
1. 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.
2. the energy coordination of multilevel SPD
3. determine the discharge current path
4. after correct installation, it can work steadily for a long time. If it is found that the transmission performance of the system is reduced or the signal is interrupted due to the cause of surge protection, it should be maintained or replaced in time.
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.
