PV Arrestors

Delta silicon arrestors comply with all requirements of photovoltaic systems.
1. Deltas do not draw continuous current.
2. Deltas consume no power during stand-by.
3. Delta's clamping voltage does not change with age.
4. When Deltas fail, they fail to open circuit to permit continued operation of PV systems.
5. Deltas contain no current limiting fuses or resistance.
6. Deltas are fire resistant.
