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 5-Pin, station and well-type protectors that utilize Gas Discharge Tube solid state Thyristor and Multi-Stage Protector (MSP®) 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 patented MSP® technology in the 2410 series 5 pin protectors and the DigiGuard 455HS and 155HS station protectors as well as in the new 2360 IPA station protector. MSP® technology is a hybrid protector assembly, 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 GDT and the reliability and safety our unique failsafe. MSP® devices have 10 times the surge life of standard GDT protectors.
