Scope: Professional fuses are generally designed for use in installations where only professional personnel can access and replace the fuse. Professional fuses are generally designed for use in installations where only professional personnel can access and replace the fuse. Unless otherwise specified in this part of GB/T 13539, fuses used by professionals who meet the requirements of the following fuse systems shall also comply with the requirements of IEC 60269-1. This part consists of the following fuse systems, each of which refers to a specific example of a standard fuse for professional use. -- Fuse system A: knife contact fuse (NH fuse system); -- Fuse system B: knife contact fuse with striker (NH fuse system); -- Fuse system C : Strip fuse base (NH fuse system); -- Fuse system D: Busbar-mounted fuse base (NH fuse system); -- Fuse system E: Bolt connection fuse (BS bolt connection fuse system); -- Fuse system F: cylindrical cap fuse (NF cylindrical cap fuse system); -- Fuse system G: offset contact knife fuse (BS clamping fuse system); --Fuse system H: "gD" and "gN" characteristic fuses (J, T and L time-delay and non-delay fuse types); --Fuse system I: gU wedge-shaped contact fuse ; -- Fuse system J: "CC class gD" and "CC class gN" characteristic fuses (CC class time-delay and non-time-delay fuse types); -- Fuse system K: Bolt-connected knife-type contacts gK fuse-links (main fuse-links for high current ratings from 1 250 A to 4 800 A).
