Catégory D1 /C1 /C2 /C3 surge protection unit DLC-06D2

for data and telecommunication linesfor signal transmissionfor telecommunication networks

Description
The DLC compact surge protective device DLC-06D2 is a non-pluggable monobloc unit designed to protect 1-pair telecom, data and industrial signalling lines from lightning and transient overvoltages. It is mounted on a symmetrical 35 mm DIN rail inside customer distribution or control panels. Available in D2, D3 and D3G variants to address floating lines, full-mode protection and signalling-ground protection respectively.
