This series of fuses are suitable for electrical installations with an AC frequency of 50Hz, a rated voltage up to 1200V, and a rated current up to 630A. There are three types of fuses with different structures. One is used for overload and short-circuit protection (gG) in electrical circuits. Another type as short-circuit protection (aR) for semiconductor equipment; It can also be derived as motor short-circuit protection (aM).The rated breaking capacity of this series of fuses is up to 80kA.This series of fuses comply with the national standard GB13539 and the International Electrotechnical Commission standard IEC60269.
