A device for protecting electronic equipment and communication lines from high voltage surges.
Ceramic arresters are surge protection devices that utilize discharge phenomena (Gas Discharge Tube: GDT). Since their commercialization, they have been widely used for lightning surge protection in communication and signal lines, and now we offer a rich variety of over 100 products. If you cannot find the shape or voltage type you are looking for, please feel free to consult us. There is a concern that using a GDT alone in power circuits may lead to continuous current flow. We recommend considering the use of AV11, 13, 14, and AV3P1, 2 in combination with varistors.
