Product Details

Usage categories

“gG/gL” Indicates a fuse-type isolating switch for general line protection with a full range of breaking capabilities.

Structural features of fuse link

The fuse link is a variable cross-section melt made of copper sheets and is encapsulated in a high-strength fusion tube. The fuse tube is filled with chemically treated high-purity quartz sand and special chemicals as arc extinguishing media. The two ends of the melt Use spot welding to securely electrically connect the contacts.

Application

This series fuse is suitable for AC 50Hz, rated voltage to 800V, rated current to 315A, for overload and short circuit protection in electrical wiring(gG/gL).Because of different melting tablets,it also may derive for protecting the semiconductor device and its complete set installment from short circuit(aR/gR/gs/gtr)、as well as the electric motor from short circuit(aM). The rated breaking capacity up to 50kA. They conform to GB13539.2 and IEC60269-2.
