  • Kevin wiring can be realized; the structure is rigorous, the installation is convenient, and the maintenance is simple

Use and maintenance

After the power module surge protector fails, the green indicator on the indicator window will turn red, and the protector should be replaced immediately.

In the normal use of this surge protector, especially during the thunderstorm season, the grounding system of the surge protector should be checked in time to keep it in good grounding condition, otherwise the protection effect of the surge protector will be affected to varying degrees. When the grounding wire PE is open, the surge protector will be disabled.


1 This power module surge protector can be combined according to different requirements and applied to single-phase and three-phase TT/TN/IT power supply systems to meet the protection requirements of different power systems. When installing on the 35mm rail, the Kevin is preferred. Wiring method can also be used as follows.

2 The surge protector should be installed after the fuse of the power supply line. The capacity of the fuse should not exceed 315A GL/gG. If this value is exceeded, a 315A GL/gG fuse should be added to the surge protection branch.

3 According to the logo of the protector, the wiring connection shall be as follows: the insulated copper wire with a cross-sectional area of not less than 10mm2 and the withstand voltage not lower than 500v AC, the length of the Boxian length of 13-15mm shall be as short as possible and not more than 0.5m. Meet the requirements of relevant standards.
