GB13539 AC 50Hz Cylindrical RGS Fuse Link High Voltage Bolt Connected

Product Description

RGS Offset Round Pipe Spiral Rapid Fast Acting Bolt Connected HV DC Cylindrical Fuse Link

Application

This series of fuse-links are suitable for electrical installations with AC 50Hz, rated voltage to 1200V, and rated current to 630A. There are three types of melts with different structures. One is used for electrical circuit overload and short-circuit protection (gG); the other is used as a semiconductor Short-circuit protection (aR) of electrical equipment; can also be derived as motor short-circuit protection (aM).

The rated breaking capacity of this series of fuse-links is up to 80kA.

This series of fuse-links complies with the national standard GB13539 and the International Electrotechnical Commission standard
IEC60269.

Structure Features

The variable cross-section melt made of pure copper sheet/silver sheet (or wire) is encapsulated in a melt tube made of high-strength porcelain or epoxy glass cloth tube; the melt tube is filled with chemically treated high-purity quartz sand as a heat sink. Arc medium. The two ends of the melt are firmly electrically connected with the end cap (or the contact knife connection plate) by spot welding. The fuse can be equipped with a striker. When the fuse is blown, the striker will act immediately, push the micro switch, send out various signals and automatically switch the circuit.
