Key Product Benefits

• Heat activated fail-safe mechanism provides additional protection
• Available with test points to access the outside plant
• Prevents costly damage to circuitry and extends equipment life
• Protects personnel from dangerous voltage surges

Tii 5-pin Gas Tube with PTC modules are dependable plug-in devices that guard sensitive telecommunications systems from dangerous voltage surges. The three-element GDT with 4 Ohm (nominal resistance) PTCs provide both overvoltage and overcurrent protection. This prevents destructive line-to-line overvoltages and sneak currents from reaching valuable telecom equipment. The combination of GDT and PTCs provide excellent electrical protection while minimally affecting high frequency DSL and ISDN signals.
