Bottle Type Cylindrical Porcelain Screw Ceramic Fuse Link DC Low Voltage Fast Speed
Application of Bottle Type Cylindrical Porcelain Screw Ceramic Fuse Link
This series of fuse-links is suitable for AC 50HZ, rated voltage to 1140V, rated
Current up to 630A, mainly used in electrical installations for line overload and short-circuit protection (gG/
gL); can also be derived as short-circuit protection (aR) for semiconductor devices and short-circuit protection for motors
Protection (aM).
The rated breaking capacity of this series of fuse-links is up to 50kA.
This series of fuse-links comply with the national standard GB13539 and the International Electrotechnical Commission standard IEC60269.
Structure Feature of Bottle Type Cylindrical Porcelain Screw Ceramic Fuse Link
The variable cross-section melt made of pure copper/silver sheet (or wire) is encapsulated in a melt tube made of high-strength porcelain; the melt tube is filled with chemically treated high-purity quartz sand as the arc extinguishing medium. There is a fuse indicator on the fuse end cap. When the fuse is blown, the indicator pops up immediately, indicating that the fuse has been blown.
