Surge Protection Terminal Blocks
for Telecom/Signal/Data Bus Systems, 4-Wire, 2-Pair

Three Pole Side View of DIN Rail Surge Protection Device This group of surge protection terminal blocks is designed for installations in category location B or C (ANSI/IEEE C62.41), or directly upstream near the protected devices. Protection is afforded to four single lines of telecom/signal/data 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 UL497B, IEC 61643-21:2000+A1: 2012 criteria. When data networks are configured to support telecom or signal systems or video transmissions, think ASI EZ as your EZ solutions provider.
