Series 3404 lightning EMP protectors Miniature gas discharge tube (GDT) technology Description HUBER+SUHNER miniature gas discharge tube protec- tors are designed to protect against multiple electro- magnetic threats including SURGE, NSL, ESD or (H)EMP. The special design guarantees an excellent dynamic protection performance. It includes a fixed integrated gas discharge tube. Miniature GDT protectors have a bulkhead feed-through design and can be easily installed instead of a standard waterproof bulkhead coaxial connector to harden existing equipment. Features • Waterproof interface even in un-mated conditions • Low contact resistance between protector body and mounting wall • Space saving inline design • Broadband DC to 3 GHz • Surge current handling capability up to 5 kA (8/20 µs) • DC continuity for remote powering • Fix installed GDT, static spark over-voltage nom. 150 V • In conformity with the LPZ concept at the boundar- ies from 0B – 1 and higher Different or additional protectors need to be applied for lightning protection.
