Working principle

Modularization---Replacing the protector dispense without shutting off the power
High Breaking Capacity---Max. Breaking capacity can endure 100KA(8/20 s)
High Speed---Tripping time less than 25ns
Status Show---color of status window show the working status of protector
Green(Normal) Red(fault)Circuit system will bring the strong pulse voltage due to the Thunde r strike of other reas ons, which
will destroy the electric equipment. Under popularization of computer and Micro-elect aronics, pe ople 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.

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,
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.YE1 specification
