C-2420 Series 5-Pin Gas Discharge Tube (GDT) Protector

The CNI C-2420 overvoltage protection modules utilize a high-efficiency gas discharge tube with a Switch-Grade Fail-Short mechanism to provide robust and reliable surge and thermal overload protection is competitively priced. The C-2420 Series is based on a three terminal common chamber GDT. This design provides greatly improved and balanced turn-on characteristics for overvoltage protection. The GDT is UL listed for use without a back-up device. Air back-up devices can become contaminated; the circuitry of the C-2420 eliminates the air back-up gap and thus the possibility of its contamination. Our Switch-Grade Fail-Short device provides more reliable thermal overload protection compared to commonly used solder pellet or insulation burn-through designs. 

The C-2420 Series 5-pin protectors can be used universally for broadband voice and data circuits including ADSL, ADSL2+, VDSL,VDSL2 and high-speed Ethernet. The C-2420 Series is an economical, reliable and low capacitance choice for overvoltage protection of copper pair circuits.
