All Bourns® Telephone Protectors are designed to provide highly safe and reliable protection against lightning surges, power-cross conditions and ground-potential rises.

The product line includes station and well-type protectors that utilize Gas Discharge Tube, Multi-Stage Protector (MSP®) and TBU® High-Speed Protector (HSP) technologies to provide primary protection for electronic equipment of twisted-pair circuits in NIDS, remote terminals, pedestals, distribution terminals or at the customer's premises.

Bourns offers our MSP® technology in the Digi-Guard™ Model 2377-45 and 2378-35 station protectors as well as in the 2360 IPA station protector. MSP® technology is a hybrid protector assembly, which contains both solid state and the GDT protection components with our "switch-grade fail-short". This technology provides the fast turn-on advantages of solid-state with the robustness of GDT and the reliability and safety of our rugged failsafe. MSP® devices have 10 times the surge life of standard GDT protectors.

The TBU® HSP is utilized for advanced overcurrent protection.
