Ex RF surge protective devices
HUBER+SUHNER Ex surge protective devices are approved for use in potentially explosive atmosphere or hazardous locations and areas of Zone 2 (gas) and Zone 22 (dust) and provide reliable prevention against dangerous overvoltage surges on coaxial lines. This includes all kinds of interference, e.g. resistive, magnetic field and electric field coupling, caused by lightning strikes, switching and other natural or manmade electrical effects. This way, the operator of active equipment is not only protected from financial losses caused by the need of replacing the equipment, but also avoids downtime of the system after a possible event. This is specifically important in environment where access to equipment is difficult, dangerous and expensive, as on an oil platform for instance.
