Square Pipe Fuse Links With Knife Contacts

Protection against overload and short-circuit in electric lines(type gG),also available for protection of semiconductor parts and equipments against short-circuit(type aR) and protection of motors(type aM).
Rated voltage up to 1140V;Rated current up to 1250A;Working frequency 50Hz AC;Rated breaking capacity up to 120KA.Compliant with GB13539 and IEC269.

Variable cross-section fuse element made from puie copper or silver sealed in cartridge made from high-duty ceramic.Fuse tube filled with chemically treated high-purity puartz sand as arc-extinguishing medium.Dot-welding of fuse element ends to the terminals ensures riliable electric coonnection and forms insert knife type contacts.Striker may be attached to the fuse link to provide immediate activation of microswitch to give various signals or cut the circuit automatically. Indicator or striker may be attached to the fuse link to show cutout of fuse or to give various signals and to cut the circuit automatically.
