ABOUT CITEL
Since 1937, CITEL has protected critical equipment and systems from transient overvoltages caused by lightning and switching events. Our surge protection devices (SPDs) help ensure operational continuity where downtime is not an option.
Today’s industrial environments rely on sensitive electronics more than ever. As industrial control panels and automated systems grow more complex, so does their vulnerability to surges. CITEL provides robust surge protection for these facilities, backed by UL certifications.
We design and manufacture millions of SPDs each year, meeting local standards and supporting clients who understand the risks transients pose to sensitive electronics. Whether standard or custom, our solutions are built to match the specific requirements of each application.
