Delta silicon arrestors comply with all requirements of photovoltaic systems.

  • Deltas do not draw continuous current.
  • Deltas consume no power during stand-by.
  • Delta's clamping voltage does not change with age.
  • Delta arrestors fail open circuit to permit continued system operation.
  • Deltas contain no current limiting fuses or resistance.
  • Deltas are fire resistant.
