Features Compact, industry standard footprint Balanced TRIGARD protection Meets test requirements of Telcordia UL Listed per UL 497 (File: E53117) GR 974, GR1361, SR 5165 and RUS PE-80 Reliability is improved by elimination of the Telcordia Analysis report DA-1843 air Back-Up-Gap (BUG) Extended service life Quick response High current handling 155G Series Heavy-Duty Station Protector Bourns Model 155G Balanced Gas Discharge Tube Protector is an economical choice for protecting copper pair voice-band and high- speed data circuits. The 155G utilizes Bourns proprietary Gas Discharge Tube for extended surge life and a patented Switch-Grade Fail-Short mechanism for thermal overload protection. Bourns P/N 2378-35-G can be used universally for POTS and high speed data, such as ADSL, ADSL2+, VDSL, VDSL2, other xDSL protocols and high-speed Ethernet. Bourns MSP technology provides unparalleled overvoltage protection with low loss on paired copper communications circuits. The Model 155G is a reliable and economical choice for overvoltage protection of paired copper communications circuits. It exceeds all Cat5 requirements. Characteristics Test Methods per IEEE C62.31, UL 497, RUS PE-80, CSA C22.2, Telcordia GR 974 and 1361.
