It is typical that transient voltage surges from both external and internal sources directly affect the performance and life expectancy of electronic equipment. Products having a printed circuit board inside, from electronic lighting ballasts to computer servers, may be susceptible to transient voltage surge damage. As microprocessors and components that make up this equipment grow smaller and faster with each new generation, their susceptibility to transient voltage surge damage becomes ever greater. The full-featured GE TR Series TVSS line with its advanced monitoring, disconnect and enclosure options has been designed to handle the highest levels of surge activity found in the most demanding commercial and industrial facilities. These units are ideal for both new and retrofit applications where performance cannot be compromised. GE engineers design and build transient voltage surge suppressors in our state-of-the-art lab and production facilities. Extensive testing is performed at GE and third-party test labs across North America.
