ITW Linx UP3B-235 UltraLinx 66 Block Surge Protector Model Overview
UP3B-235 UltraLinx 66 Block from ITWLinx is a voice high-speed data 66 block surge protector with Sneak Current Protection, which protects against fires caused by overloads and power crosses. The Single Pair Protection method protects only the lines requiring protection. The Solid-state Protection automatically resets without user intervention and provides the fastest response to transient voltages by quickly diverting damaging surges to ground.
