Working principle

Modularization---Replacing the protector dispense without shutting off the powerHigh Breaking Capacity---Max. Breaking capacity can endure 100KA(8/20 s)High Speed---Tripping time less than 25nsStatus Show---color of status window show the working status of protectorGreen(Normal) Red(fault)Circuit system will bring the strong pulse voltage due to the Thunde r strike of other reas ons, whichwill destroy the electric equipment. Under popularization of computer and Micro-elect aronics, pe ople paymore attention on the over-voltage protection of low voltage circuit system. YE1 type Surge ProtectiveDevice(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 lineconnecting 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 putthrough within ns (Time unit)and lead the surge overload voltage into the earth to protect the electricdevice on the wire. After make the surge voltage disappear, the SPD will change back to the resistancestatus which not effect the normal work of circuit system.
