Applications
- Protection against overload and short-circuit in electric lines(type gG), also available for protection of semiconductor parts and equipment’s against short-circuit (type aR) and protection of motors(type aM).
- Rated voltage up to 1140V; Rated current up to 630A; Working frequency 50Hz AC; Rated breaking capacity up to 50KA. Compliant with GB13539 and IEC269.
Design Features
- Variable cross-section fuse element made from pure metal sealed in cartridge made from high-duty ceramic. Fuse tube filled with chemically treated high-purity quartz sand as arc-extinguishing medium. Indicator springs out when fuse cuts to give caution.
