Who's CITEL ?
Since 1937, CITEL has been keeping the world's critical networks and equipment protected from transient overvoltages. Whether a large magnitude lightning strike or the relentless barrage of switching events, our surge protectors keep sensitive electronics safe and operations uninterrupted.
CITEL's thorough understanding of local standards and regulations, along with a continuous investment in R&D, inspire us to design, manufacture and supply millions of SPD’s each year to our clients who are conscious of the danger transients pose and actively take steps to eliminate the threat.
CITEL develops many of our critical surge protection components internally including gas discharge tubes, thermally protected varistors and high-energy varistor assemblies. This means that CITEL has expertise into every minute detail of the parts that make up an SPD.
Our teams all over the globe are proud to bring our clients a comprehensive product range of surge protectors that is unmatched in customer service and product quality.
