2377-45 Series Digi.Guard – MSP ? Maximum Duty Station Protector

Bourns ? Model 455HS Multi-Stage Protector (MSP ? ) is a new generation telecommunications station protector designed to be

the best all around choice for protecting copper pair voice-band and high-speed data circuits. Combining the strengths of Gas

Discharge Tube (GDT) and solid state overvoltage protection, the Model 455HS MSP ? integrates three advanced technologies:

our proprietary advanced GDT, precision matched metal oxide varistors (MOV), and a patented Switch-Grade Fail-Short

mechanism. The 2377 series offer superior service life, far exceeding Telcordia standards.

Bourns ? 2377-45 can be used universally for POTS and high speed data, e.g. ISDN, ADSL, ADSL2+, VDSL, VDSL2, other xDSL

protocols and high speed Ethernet. Bourns ? MSP ? technology provides unparalleled overvoltage protection with low loss on paired

copper communications circuits. The Model 455 is the most economical, reliable and effective choice to protect paired copper

communications circuits. The IDC version, with environmental sealant, provides additional ease of installation and protection against

corrosion.
