Product Description

3RB-8S Gas Discharge Tube 75V 90V 150V 230V 250V 350V 420V 470V 600V 10KA 8x10mm GDT Surge Protector Arrester

 

Description of 3RB-8S Gas Discharge Tube

 

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.
