LPXT-WM-TERM series of surge suppressors are a high-speed, high-current solid state device designed to protect RS 422, 4-20 ma Double Wire Pair (4-Wire) configurations and other balanced pair applications from transient over voltages. The LPXT-WM-TERM series uses only silicon suppression components. It connects to the equipment and line via two (2). Six (6) position terminal blocks. Note: "EQUIP GND" connection should be kept as short as possible and utilize the largest gauge wire possible.
