Features: Large through-current capacity, long service life. Adopt multi-level protection, low voltage, good protection effect. Low insertion loss, excellent transmission performance. Built-in fast semiconductor protection device, nanosecond response speed. Energy saving, environmental protection, rack structure for easy installation. Scope of Application: The audio telephone lightning protector (phone lightning arrester) is designed according to IEC and international standards, mainly used for lightning and overvoltage protection of telecommunication data communication signal lines and their equipment (such as telephone, SPC exchange, fax machine, ADSL, MODERN), easy to install, no need for special maintenance. Specifications: Condition: Brand New Working Voltage Uc: 110V Limited Voltage Up: 180V Through-current Capacity 8/20µs: 5KA Maximum Through-current Capacity 8/20µs: 10KA Adaptive Transmission Rate: 2Mbps Temperature Range: -40°C ~ +80°C Installation Method: In series Insertion Loss: =0.5dB Response Time: =1ns Interface Form: RJ11 Protection Level: IP20 Material: Metal Color: Shown as picture Size: Approx.80*25*25mm/3.1*1*1in Package List: 1 * Telephone Surge Protector 1 * User Manual See more

Tips: Please look for the interface and connection method; The grounding should be reliable, and the grounding wire should be short, thick and straight to reduce the influence of distributed inductance on Thunder discharge; this product does not require special maintenance. When the system works, thesurge protector arrester can be removed. If it can be restored, surge protector arrester should be replaced. Fast response: Built-in fast semiconductor protection device with nanosecond response speeds.When the apex current or voltage is suddenly generated in the electrical circuit or communication line due to external interference, the surge protector can conduct the shunt in a very short time, thereby avoiding the damage of the surge to other equipment in the circuit. Small insertion loss and superior transmission performance: aluminum alloy shell design, standard interface, no rust, oxidation, energy saving, environmental protection, rack structure. Easy to install, surge protector arrester is connected between the protected device and the signal communication. Large through-current capacity, multi-level protection: large circulation, multi-level protection, low voltage, good protection effect, suitable for surge protection of signal, control and power supply installed in video surveillance cameras, can protect your well The equipment is protected from thunderstrike and surges and damage caused by overvoltage of the power grid. Grounding scheme to avoid signal interference: Single-channel power signal arrester can prevent thunder waves from entering the system from the outdoor signal line, thus protecting the important equipment such as computer network and safety monitoring system, and avoiding signal interference.
