Features Applications ■ ■ ■ ■ ■ ■ ■ ■ Board mount 330 V surge protector UL Recognized Economical, reliable choice for all paired copper communications circuits ■ Solid-state responsiveness combined with robust GDT Telecommunications High speed data networks Hybrid fiber-coax networks Broadband powered networks 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.
