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.


  • 40,000 amp peak capability, each 120 VAC leg
  • 210 VAC, continuous 5-minute temporary overvoltage clamping capacity
  • Lowest reliable voltage clamping level
  • Safety fusing, both 120 VAC legs
  • Patented LED “unit good” indicators, both 120 VAC legs
  • Fireproof and explosion-proof polycarbonate glass-fiber-reinforced enclosure with matching mounting connector
  • Sealed unit except for mounting connector wiring opening
  • For less inductance, 10# AWG tinned wires
  • Electrical and Environmental Specs
  • Triple surge electrical chart

Telephone Line Surge Arrestor Specs
