Features High current handling Patent 6,327,129 Balanced TRIGARD Compact, industry standard footprint Listed per UL 497 (File: 53117) Meets test requirements of Telcordia GR 974, GR1361, SR 5165 and RUS PE-80 Reliability is improved by elimination of the air Back-Up-Gap (BUG) Telcordia Analysis report DA-1843 Multi-Stage Protection (MSP ) Quick response 155HS Series Digi.Guard II - MSP Heavy Duty Station Protector Bourns Model 155HS Digi.Guard II Multi-Stage Protector is a new generation telecommunications Station Protector designed to be the best all around choice for protecting copper pair voice-band and high speed data circuits. Combining the strengths of Gas Tube and solid-state protectors, the Model 155HS integrates three advanced protection technologies: a proprietary sixth-generation Gas Tube, a precision matched metal oxide varistor and a patented Switch-Grade Fail-Short mechanism. Bourns 2378-35 can be used universally for POTS and high speed data, e.g. ISDN, 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 155 is the most economical, reliable and best performing choice for overvoltage protection of paired copper communications circuits.
