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 off er superior service life, far exceeding Telcordia standards.

technology provides unparalleled overvoltage protection with low loss on paired
copper communications circuits. The Model 455 is the most economical, reliable and eff ective choice to protect paired copper
communications circuits. The IDC version, with environmental sealant, provides additional ease of installation and protection against
corrosion.
