It relates to a single module overvoltage suppressor with a built-in surge counter. In particular, this module can be connected to phase and neutral wire, neutral wire and ground wire or phase and phase, phase and ground, and when combined, it can be composed of single phase three wire type or three phase three wire, three phase four wire transient over voltage suppressor. In another aspect, the present invention relates to the provision of an overvoltage suppressor that minimizes internal circuit impedance by adopting a double copper surge surge.

The present invention is designed to improve the above problems.

Even if the entire abnormal voltage suppressor is not replaced, the replacement cost can be reduced by reusing the damaged module. In addition, a surge board that minimizes internal impedance is adopted by using a double copper plate structure of a printed circuit board on which various protection elements are disposed. In addition, the operation indicator lamp is built-in to improve the function of the suppressor and the surge counter is built in so that the number of incoming surges can be added to the naked eye to check.In one module, individual transient abnormal voltage suppressors, phase and neutral wires, It is an object of the present invention to connect a neutral wire and a ground, or a phase and a phase, a phase and a ground, and to configure a single-phase three-wire, or three-phase three-wire, three-phase four-wire transient abnormal voltage suppressor.
