Surge current capacity - FirstSurge offers three different surge protector sizes based upon geographic location and thunderstorm activity
3-Stage diagnostics - when FirstSurge wears out, the protection status LEDs extinguish, an audible alarm beeps and a red service light flashes to warn the homeowner
Balanced VPR protection - all primary paired conductors are surge protected in a balanced manner with 600 V UL1449 VPR
Ground Reference Monitoring - GRM diagnostics monitor the health of a home's neutral to ground bond and alert the homeowner if the bond becomes loose, preventing a potential safety issue
