2377 MSP®/TBU® Series DigiGuard® Station Protector
Bourns® 2377 MSP®/TBU® series is a new generation telecommunications station protector designed to be the best choice for
protection of high-speed network data circuits. Bourns® 2377 MSP®/TBU® series protectors integrate four advanced technologies:
our proprietary advanced TRIGARD® GDT, precision matched metal oxide varistors (MOVs), a switch-grade fail-short mechanism, and
our TBU® (Transient Blocking Unit) technology which protects the circuit by rapidly switching to a blocking state. These technologies
are combined to provide robust overvoltage and fast, resettable sneak current protection with extremely low energy let-through.
Additionally, the MSP®/TBU® series has very low loss characteristics, making it the ultimate choice for protection of sensitive, high
speed communication lines.
A continuous DC bias such as sealing current or remote powering (span powering) can hold the TBU® device in a high resistance
blocking state after the fault has passed. The TBU® device can be reset by momentarily disrupting the loop current or providing a
low voltage (Vreset) condition on the line.
