This standard specifies the rated value, temperature rise under normal use, dissipated power, time-current characteristics, breaking capacity, interrupted current characteristics, I2t characteristics, arc voltage characteristics, Test and sign. This standard applies to fuses used in equipment with semiconductor devices in circuits with a rated AC voltage not exceeding 1200V or a DC rated voltage not exceeding 1500V. Note: ① In most cases, a part of the combined device is used as the base of the fuse. Due to the wide variety of equipment, it is difficult to make general provisions. Whether combined equipment is suitable for use as a base for fuse-links should be negotiated between the user and the manufacturer. However, when independent fuse bases or supports are used, they shall comply with the relevant provisions of GB13539.1. ②This kind of fuse is usually called "semiconductor fuse".
