Surge Protective Device Panel (SPD Panel) Reset Breaker
SPD refers to "Surge Protective Device," which has traditionally been called a "lightning arrester."
SPD is one type of "surge protective device" that protects power equipment in power generation and transmission systems, demand devices of consumers receiving power, wired communication lines, antenna systems, communication equipment, and so on, from transient overvoltages caused by phenomena such as lightning. In Japan, the installation of SPDs for high-voltage transmission and distribution systems has been mandatory for some time, and there have been specific standards for them. However, there have been no specific regulations for those installed in consumer demand devices, and their application has been based on the voluntary judgment of each manufacturer and consumer.
