<p>In the realm of industrial and commercial applications, ensuring network integrity is crucial. This Network Protector serves as a reliable solution for safeguarding your infrastructure against electrical disturbances. Designed with precision, it offers robust protection at a rated voltage of 4 VAC and accommodates both per line and common mode currents, handling up to 5 kA and 10 kA respectively.</p><p>The device connects through eight RJ45 ports, making integration into existing systems straightforward. Its IP20 degree of protection indicates that while it is protected against solid objects larger than 12 mm, it should be installed in environments where exposure to moisture or dust is limited.</p><p>Sized for efficiency, the Network Protector fits seamlessly into rack systems with dimensions of 483 mm in length, 20 mm in width, and a height of 88 mm. Despite its sturdy steel construction ensuring durability under various conditions, it maintains a manageable weight of just 1.85 kg.</p><p>Operationally versatile across extreme temperatures ranging from -40 to 70 degrees Celsius, this protector is built to perform reliably whether you&#39;re dealing with harsh winters or sweltering summers. It supports humidity levels between 5% and 95%, further enhancing its adaptability to diverse environmental conditions.</p><p>The Network Protector&#39;s compliance with several standards—IEC 61643-21, AS/NZS 1768 among others—underscores its reliability and quality assurance. The inclusion of UL 497B certification ensures adherence to stringent safety standards while ITU-T K.44 compliance guarantees performance under telecommunication conditions.</p><p>With an impressive response time of less than five nanoseconds (ns), this unit efficiently mitigates transient overvoltages before they can cause damage. The voltage protection level stands at less than 0.02 kA for line-to-line connections and less than 0.35 kA for line-to-earth scenarios—a testament to its protective capabilities against potential surges.</p><p>Additionally, it withstands lightning impulse currents up to either one or two kiloamperes (kA), providing peace of mind during stormy weather when electrical surges are more prevalent.</p><p>Overall, this Network Protector embodies a balance between technical sophistication and practical application within industrial settings—offering comprehensive protection without compromising on ease-of-use or installation flexibility.</p>
