Function

This equipment mounts the arrester of AC100V by two methods.
The arrester is mounted between live-playground, live-neutral, and neutral-grandeur at one power supply method.
The arrester uses the ZnO element with an excellent non-straight-line-resistance characteristic in which the zinc oxide etc. is assumed to be a principal ingredient.
Moreover, it is a plug-in structure, and it is possible to exchange it from the front side easily. The watching check is possible from the transparent window for the check with built-in the separation device.
