Protection of data lines (Ethernet, Coaxial & Phone lines) ensures complete protection of your equipment from surges. It is very important to protect your equipment from &156;back door&157; electric surges traveling through data lines, as they can be as damaging to your equipment as surges traveling over power lines.nn Reduces line noise that can cause data loss & keyboard errors.nn APC surge protectors undergo stringent testing by IEEE, & are awarded ""let-through ratings"", which indicate the maximum voltage level that can possibly reach your equipment after a surge or voltage spike has passed through an electric surge protector. Lower IEEE let-through ratings indicate better protection & performance. The APC Essential Surge Arrest series offers optimal performance with a let-through rating of less than 330V for North American products, & a rating of less than 15% for products sold worldwide. All APC products comply with local agency safety requirements, including UL in North America & CE/ Kema/ Gost/C-tick/A-Tick/ Telepermit in their respective regions.\n\n\n\n\n\n\n\n\n\n Model: Surge Arrest\n\n\n\n\n\n\n\n\n\n\n\n\n\n
