Technical Specifications

Meter Base Surge Arrestor


120 VAC-240 VAC Surge Arrestor for residential usage. Installed at wattmeter, safely clamps and dissipates lightning induced AC line high voltage current impulses going to a residence. Also protects against AC line temporary overvoltage conditions.
