FAQ

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

The ‘gG’ designation indicates a general-purpose fuse link for cable and line protection. It can interrupt currents from the smallest melting current up to its rated breaking capacity, making it suitable for a wide range of industrial applications.

Is the red indicator on the front of the fuse important?

Yes, the red dot is a front indicator for fuse operation. When the fuse is intact and operational, the indicator is visible. After the fuse has tripped due to an overcurrent or short circuit, the indicator will pop out or change color, providing a clear visual signal that the fuse needs to be replaced.

Can this Size 2 fuse be handled while energized?

This fuse is equipped with insulated gripping lugs, which significantly improves safety during installation and removal. However, handling any electrical component in a live circuit should only be performed by qualified personnel using appropriate personal protective equipment (PPE) and a suitable fuse-pulling tool, following all local safety regulations.
