Zhongpeng Surge Protector (SPD) Product Introduction
EPO series modular surge protectors are designed in accordance with IEC and GB standards and have strong surge relief capabilities. They are used for protection at all levels of low-voltage power distribution systems, depending on different power distribution systems.
(TT/TN/IT) can choose a variety of combinations, usually installed in the lightning protection zone LPZ0 B-1 subsequent zone, with ultra-high overvoltage withstand capability.

Zhongpeng surge protector (SPD)—Advantages of tripping device
Other product trip devices
Easy-made product release device
● The rapid heat conduction of the low temperature solder joints makes the tripping more timely and accurate;
● Mechanical arc shielding to make arc extinguishing more effective (the creepage distance is as high as 12mm after disconnection);
● The tripping device does not occupy additional space, so that it does not affect the discharge capacity of the SPD;
● Ensure that the trip device operates before the MOV is damaged, so as to avoid fires caused by a short MOV.
Zhongpeng surge protector (SPD )—Process advantage
EYZAO SPD is 100% potted encapsulation
1. Better tightness; 2. The production process is complex and the cost is high; 3. Better stability, to ensure that the solder joints are free from external forces; 4. Effectively prevent the deformation of the MOV and the plastic shell to ensure its sealing and insulation performance, especially It is used in a high temperature environment .
Under the conditions of high temperature and humidity, the encapsulated MOV is more likely to degrade, and when a surge comes, the SPD is more likely to burst. |  |
Super high overvoltage withstand capability
EYZAO SPD has excellent transient overvoltage withstand capability. Under the condition of ultra-high over-voltage, it can trip safely without catching fire, and give correct instructions. It is unique in the industry.
Take the 320V SPD as an example, add (750V) on both sides of the SPD 3 times the normal voltage (230V), 2.3 times the Uc value of the SPD (320V), the state of the SPD is as follows:
The requirements of IEC61643-11 for this product are only 337V/5s tolerance and 440V/2h failure mode. EYZAO SPD far exceeds this requirement, which is of great significance in practical applications.
