All Bourns® Telephone Protectors are designed to provide highly safe and reliable protection against lightning surges, power-cross conditions and ground-potential rises.
The 3-type overvoltage 5-pins utilize Gas Discharge Tube (GDT) and Multi-Stage Protector (MSP®) technologies to provide primary protection for electronic equipment of twisted-pair circuits.
Bourns offers our MSP® technology which contains both solid state and GDT protection components with our "switch-grade fail-short". This technology provides the fast turn-on advantages of solid-state with the robustness of the GDT and the reliability and safety of our rugged failsafe. MSP® devices have 10 times the surge life of standard GDT protectors.
The TBU® High-Speed Protector is utilized for advanced overcurrent protection.
