Surge Arresters for AC networks up to 1000 V

SURGE ARRESTERS
SPB */10 PP **

SPB */10 PP ** - a surge arrester as per EN 61643-11: 2012 with a nominal discharge current of 10 kA and a maximum continuous operating voltage of UC = 280 V, 440 V, 500 V or 660 V. They provide protection against low-voltage overvoltage, they protect in low-voltage overhead power distribution systems, electrical equipment, instruments, switchgears of distribution transformers and reduce the risk of damage to in-house systems and their equipment by atmospheric and switching overvoltage in AC systems with a frequency of 48-62 Hz. The SPB surge arresters protect against the destructive effects of lightning and switching overvoltage.
