FAQ

What does the ‘gG’ characteristic mean for this Siemens 3NA6 240-6 fuse?

The ‘gG’ designation indicates a general-purpose, full-range breaking capacity fuse. It is designed to protect against both overload (the ‘g’ part) and short-circuit currents (the second ‘g’ part). This makes it suitable for a wide range of applications, including protecting cables, lines, and general industrial equipment.

Can I use this 500V marked Weber fuse in a 690V system as indicated on the Siemens box?

The Siemens part number 3NA6 240-6 is officially rated for 690V AC. While the fuse body might be a component also used for 500V applications (as marked by Weber), the complete assembly as specified by Siemens meets the 690V rating. It is crucial to always adhere to the specifications on the official packaging and datasheet provided by the primary manufacturer, which in this case is Siemens.

What is the breaking capacity of this fuse, and why is it important?

This fuse has a breaking capacity of 120kA (kiloamperes). This is a critical safety specification that indicates the maximum short-circuit current the fuse can safely interrupt without rupturing or causing a hazard. A 120kA rating is very high, making this fuse suitable for industrial systems where fault currents can be extremely large.
