Bourns MSP Series is a new generation of telecommunications protector designed to be the best all-around protection choice on
both today and tomorrow’s copper pair based communications circuits. It combines the strengths of gas tube and solid-state
protectors while eliminating their weaknesses. Bourns MSP protector series is the synergistic integration of three advanced
protection technologies; sixth generation gas tube, precision matched MOVs, and switch-grade fail-short. Working together, these
three technologies meet the challenges of the evolving high-speed network.
Bourns MSP Series can be used universally on POTS, ISDN, ADSL, SDSL, HDSL, RADSL, VDSL, 10BaseT, and T1 carrier. Bourns
MSP Series is the most economical, reliable, and best performing choice for all paired copper communications circuits.
