ECL tolerates ac mains power contact without damage

摘要

The TBU (transient blocking unit) DT series circuit protection devices 4 target high-speed protection of communications ports. They are the industry's first electronic current limiters (ECLs) designed to tolerate ac-mains power contact without circuit damage. The fast-reacting protectors do not alter the signal performance of high speed communication ports unlike high capacitance protectors. The devices provide protection against faults caused by short circuits, ac power cross, induction, and lightning surges.
