YE1-D Surge Protective Device 4 Poles

Place of Origin: Zhejiang, China
Model Number: YE1-D 4 Poles

In the system of three phase four line, there are SPD between both 3 l ive sires a nd the neut ral line connecting with the ea rth(Ref. Chart 1). Under normal con dition, the SPD is in the status of high resistance

Quantity:
Outline
Circuit system will bring the strong pulse voltage due to the Thunder strike of other reas ons, which will destroy the electric equipment. Under popularization of computer and Micro-elect aronics, people pay more attention on the over-voltage protection of low voltage circuit system. YE1 type Surge Protective Device(SPD) is the exact product to protect this kind circuit system.
 
Working principle
In the system of three phase four line, there are SPD between both 3 live sires and the neutral line connecting with the ea rth(Ref. Chart 1). Under normal con dition, the SPD is in the status of high resistance, once circuit system bring the surge over voltage due to the Thunder strike or other reaso ns, SPD will put through within ns (Time unit)and lead the surge overload voltage into the earth to protect the electric device on the wire. After make the surge voltage disappear, the SPD will change back to the resistance status which not effect the normal work of circuit system.
 
Characteristic
