Applications
This series of fuse links is mainly used in AC 50Hz, rated voltage up to 1140V, rated current up to 1250A and for pro tecting electric equipment from overload and short-circuit. It can reliably break the min. fusion current to any current wit hin 120KA.
It is also available for the protection of semiconductor parts and equipments against short-circuit (type aR) and prote ction of motors (type aM).
This series of fuse links conforms to GB13539 and IEC 60269 standards.
Design Features
It adopts the material with high quality. The arc-extinguishi ng medium is quartz sand and fuse tube is high strength ceramic. The advanced manufacturing craft work ensures the performance of small power waste, stable characteristic for the product. The outline structure and installation dime nsion joints the advanced similar products from domestic and abroad.
