FAQ

What does the 'gG' characteristic mean for this Siemens 3NA3 830 fuse?
The 'gG' characteristic indicates a general-purpose fuse link. It is designed for protecting cables, lines, and equipment against both overload (low overcurrents) and short-circuits (high overcurrents). This makes it suitable for a wide range of industrial applications.

Can I use this NH000 fuse in a size NH00 fuse holder?
Yes, NH000 and NH00 fuses are physically the same size and are interchangeable in corresponding fuse bases or switch disconnectors. The '000' is an older designation often used by Siemens, while '00' is the more standardized term, but they refer to the same physical dimensions.

What is the breaking capacity of this fuse, and why is it important?
This fuse has a high breaking capacity of 120 kA (kiloamperes). This is the maximum fault current that the fuse can safely interrupt without rupturing or causing an arc flash. A high breaking capacity is critical for safety in industrial systems where potential short-circuit currents can be very high.
