X.FV. Surge protections

Surge protections serve as protection for data and instrument lines, communication interfaces, sensors, transmitters and other electronic devices against pulse overvoltage. Explosion-proof surge protections X.FV. are designed for common applications in explosive areas. Protections type X.FV./JB solely designed for incorporation into intrinsically safe circuits. They are mainly used in large-scale operations and unprotected (outdoor) facilities, e.g. storage tanks of flammable liquids, sewage treatment plants and distillation columns in petrochemical plants.
