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 highspeed 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.
