FAQ What does the ‘gG’ characteristic mean for this Weber fuse?The ‘gG’ characteristic indicates a general-purpose fuse for full-range breaking capacity. It is designed to protect against both overload (slow-blow) and short-circuit (fast-acting) conditions, making it suitable for protecting cables, lines, and general equipment. Is this NH 1 fuse suitable for protecting semiconductor devices?No, ‘gG’ fuses are not typically recommended for protecting sensitive semiconductor devices like thyristors or IGBTs. For such applications, you should use a fuse with an ‘aR’ or ‘gR’ characteristic, which are specifically designed for ultra-rapid protection of semiconductors. Can I use a fuse holder with a blown fuse indicator with this KTF series fuse?This specific model does not have a built-in trip indicator. To use a visual or electrical indication system, you must select a fuse version that includes an indicator pin or use a fuse base that has its own monitoring capabilities compatible with standard NH fuses.
