This single pair analogue line protector uses state-of-the-art semiconductor technology to protect telecom systems and networks from the damaging effects of induced lighting, AC induction and electrostatic discharges. In the normal mode of operation, the protection module is transparent to the functioning of the telecommunication system, but when the voltages exceed the breakdown voltages, the semiconductor device activates and diverts the harmful energy away from the equipment being protected. The single line protectors are designed to interface with Krone LSA Plus' disconnect blocks, and together with the earth bars, protect applications at telephone exchanges, remote cellular sites, building entrance terminations and equipment at customer premises. Data speed: 100KHz Economical single pair protection Low residual voltage Meets industry standards Reduces down time Increases network reliablility 2 year warranty Alternative products High speed data line protector: Product No 12-00203 Optional Accessory Earth Frame: product # 12-660
