Non-Linear Resistors

Metrosil non-linear resistors are manufactured from a semi-conducting material based on silicon carbide, which has the distinctive property that its electrical resistance depends on the applied voltage. This enables them to act as an electrical “safety valve” to protect equipment and insulation from the effects of over voltages. In production for over 50 years, Metrosil has provided a reliable solution for surge protection in many applications. Metrosil discs introduction: Metrosil discs are available in sizes from 25 to 150 mm diameter. They can be supplied as plain unmounted discs or mounted on central studs either as single discs or as multidisc assemblies arranged in series or parallel. The smallest size can be supplied with suitable wire terminations and encapsulated in PVC or other materials as required. Metrosil applications: most of the applications of Metrosil make use of its non-linear properties to provide an “electrical safety valve” for protecting equipment and insulati
