Delta Lightning Arrestor
A surge arrestor helps to provide immediate, and reliable protection against any high voltage surge (such as that of a lightning strike).
The Delta Lightning Arrestors ara a type of silicon-oxide varistor, that conducts when the Voltage gets high enough. They provide surge protection of 60,000 Amp at budget pricing. This arrestor has 3 leads for positive – negative – ground, and is intended for use with DC systems up to 500V, such as small off-grid or large grid-tie solar PV arrays.
