3RA-6 Gas Discharge Tube Element 90V GDT for Lightning Surge Arrestor Protector 6mmX8.5mm 70V-800V
Description of 3RA-6 Gas Discharge Tube 70V-800V
GDT is placed in front of, and in parallel with, sensitive telecom equipment such as power lines, communication lines, signal lines and data transmission lines to help protect them from damage caused by transient surge voltages that may result from lightning strikes and equipment switching operations. These devices do not influence the signal in normal operation. However, in the event of an overvoltage surge, such as a lightning strike, the GDT switches to a low impedance state and diverts the energy away from the sensitive equipment.
Our GDT offer a high level of surge protection, a broad voltage
range, low capacitance, and many form factors including new surface
mount devices, which makes them suitable for applications such as
Main Distribution Frame (MDF) modules, high data-rate telecom
applications (e.g. ADSL, VDSL), and surge protection on power
lines. Their low capacitance also results in less signal
distortion. When used in a coordinated
circuit protection solution with PolySwitch devices, they can help
equipment manufacturers meet stringent safety regulatory standards.
