HVR offers the largest selection of SiC Varistor discs on the market. What would be a non-standard for others is a standard for us.

Our discs are designed and developed to withstand a continuous temperature rating of 200°C. This allows a unique energy rating of our ceramic.

Our advanced technology allows us to offer the most cost-effective solution to our customers. We select our discs within a very tight tolerance for each project to give the best stability. For smaller projects we have a huge stock on discs at different production stages.
