Overview

The 4330 helps suppress electrical transients traveling down the phone line before they impact the phone modem (typically our COM220 or COM320). The surge protector must be properly grounded to work. The 4330 does not include enclosure hardware; a similar surge protector, the 6362, includes this hardware.
