Abstract
The present invention discloses a varistor which comprises three parallel ceramic layers. Each of the ceramic layers has two electrodes on both sides thereof. Four leads are properly arranged between and outside surfaces of the ceramic layers to contact with these electrodes. By further providing one or two wires to connect these leads, the three- or single-phase power sources can be protected in a safer manner.
