MSP® Series - Multi-Stage Protector Sub-Assembly
Bourns® MSP® Multi-Stage Protector 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® Multi-Stage 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.
