Round Cartridge Fuse Links With Knife Contacts

Applications

• Protection against overload and short-circuit in electric lines (type gG), also available for protection of semiconductor parts and equipment against short-circuit (type aR) and protection of motors (type aM).
• Rated voltage up to 1200V; Rated current up to 630A; Working frequency 50Hz AC; Rated breaking capacity up to 80KA. Compliant with GB13539 and IEC269.

Design Features

• Variable cross-section fuse element made from pure copper or silver sealed in cartridge made from high-duty ceramic or epoxy glass. Fuse tube filled with chemically treated high-purity quartz’s and as arc-extinguishing medium. Dot-welding of fuse element ends to the terminals ensures reliable electric connection and forms insert knife type contacts. Striker may be attached to the fuse link to provide immediate activation of micro switch to give various signals or cut the circuit automatically.
