XB-SL-DH Telephone line lightning arresterDetailed product description：

Function and application scope:
The XB-SL-DH telephone line lightning arrester is produced using gas discharge tubes, varistors, and imported high-quality fast clamping semiconductor devices. Connected in series at the front end of the communication line interface, it suppresses high voltage pulses on the line and protects backend equipment from damage caused by lightning and industrial surges. With a current carrying capacity of 5KA, it can effectively prevent the data transmission system from being damaged by transient overvoltage caused by electrostatic induction and electromagnetic induction, greatly ensuring the safety of protected equipment. It is the best choice for remote transmission protection of telephone lines. Excellent anti overvoltage characteristics can provide anti-interference protection for communication equipment.
This product is suitable for communication equipment such as fax machines, modems, telephones, and program-controlled switches.

Technical Specifications:

Nominal current capacity (8/20 μ s)	5KA
clamping voltage	170/230V
Insertion wear and tear	<0.5dB
response time	<1ns
Insert resistor	<1 Ω
interface method	RJ11

Installation and maintenance methods:
At the front end of the protected equipment's line, connect the XB-SL-DH telephone line lightning arrester in series, connect the 2-3 input terminal IN to the telephone transmission line, and connect the output terminal OUT to the protected equipment. Make a reliable electrical connection between the lightning arrester grounding terminal and the ground wire.
If it is found that the installed lightning arrester cannot transmit data normally, remove the lightning arrester and directly connect it to the equipment. If it still cannot transmit normally, the lightning arrester is intact and other reasons should be investigated.
