Over voltage protection Varistor 25D561K Diameter 25MM 560V
Varistors 25D561K are mainly used to limit harmful atmospheric overvoltage and operating overvoltage, can effectively protect the system or equipment: 1. In electric power industry, pressure sensitive material is often used to make arrester valve plate. High voltage insulators made of zinc oxide pressure-sensitive material can realize both insulation and transient over-voltage protection. 2. In electronic circuit, with over voltage protection, lightning protection, surge current suppression, peak pulse absorption, limiting, high voltage arc extinction, noise elimination, semiconductor device protection and other functions.
