Screw Base Type Fuse Links

Applications

Protection against overload and short-circuit in electric lines(type gG), also available for protection of semiconductor parts andequipments against short-circuit (type aR) and protection of motors(type aM).
Rated voltage up to 1140V; Rated current up to 630A; Workingfrequency 50Hz AC; Rated breaking capacity up to 50KA. Compliantwith GB13539 and IEC269.

Design Features

Variable cross-section fuse element made from pure metalsealed in cartridge made from high-duty ceramic. Fuse tube filledwith chemically treated high-purity quartz sand as arc-extinguishingmedium. Indicator springs out when fuse cuts to give caution.
