Surge Protection Terminal Blocks
for High Frequency Bus System, 4-Wire

Three Pole Side View of DIN Rail Surge Protection Device This group of surge protection terminal blocks are designed for installations in Lightning Protection Zones (LPZ) OA-2 and higher, or directly upstream near the protected devices. Protection is afforded to four single lines of high-frequency bus systems or video transmissions. Two stage circuit protection is achieved by incorporating the use of GDT (Gas Discharge Tube) and a Transient Absorption Diode. The modules are easily installed on 35 mm DIN Rail and are only 7 mm wide, providing effective use of limited space. Two types are available that support either 5 V or 24 V nominal voltages.

These devices are built in accordance with IEC 61643-21:2000+A1: 2008 criteria. When data networks are configured to support high-frequency bus systems or video transmissions, think ASI EZ as your EZ solutions provider.
