Prosurge announces compact size TVSS/UL surge panel with 400kA to 600kA per phase, and also meet lightning current capacity (10/350 us) 40~60kA per phase, EN/IEC 61643-1/11 class I test.
Surge Protective Devices (SPD) are used to protect electrical equipment against surges (overvoltages) caused by lightning or switch of heavy duty machines (many people may ignore this). It may take some technical background when selecting a proper surge protective device as there are various technologies and regulations. The IEC 61643 standard defines 3 types of [...]
SPD is a device designed to limit surge energy to electrical equipment. It does this by diverting or limiting surge current. An SPD is wired in parallel to the equipment it is intended to protect. Once the surge voltage exceeds its designed rating it “begins to clamp” and starts to conduct energy directly to the [...]
