Can AC surge arresters be connected in parallel in a DC circuit?

Can Anxun lightning protection AC lightning protection device be connected in parallel in DC circuit DC system?

The AC power surge arrester is suitable for power protection of power distribution rooms, power distribution cabinets, switch cabinets, AC power distribution panels and other systems. Generally, the AC surge arresters of lightning arrester companies are recommended to be installed in the AC system. Can the device be used in a DC system?
First of all, we need to understand the structure and composition of the AC surge arrester. At present, most of the components of the AC surge arrester on the market are varistors.

The varistor AC surge arrester is also called the voltage limiting surge arrester. We know that the varistor can be used in both AC and DC, but the same varistor is suitable for different AC and DC voltages, such as the maximum continuous working voltage The 75VAC varistor generally has a maximum continuous DC working voltage of 110V, so if it is a varistor-type AC surge arrester, there will be no problem with the surge arrester installed on a DC system of the same voltage level, and it can work normally.
However, it is best to consult the lightning protection device manufacturer to understand the corresponding relationship between the AC and DC of the lightning protection device, and choose the appropriate lightning protection device.
