FAQ

What is the difference between gL and gG characteristics?

For modern fuses, the gL (cable and line protection, old German standard) and gG (general purpose fuse link, international standard) characteristics are functionally identical. A gG fuse can replace a gL fuse without issue in most applications.

Can I use this NH0 fuse in an NH00 fuse base?

Yes, NH fuses of size 0, 00, and 000 are often mechanically interchangeable and can fit into the same fuse base. Always ensure the electrical ratings are appropriate for your application.

What does the ‘KTF’ in the model number mean?

KTF is an abbreviation from German: ‘Kennmelder-Traggriff-Frontanzeiger’. It signifies that the fuse is equipped with a front-facing blown-fuse indicator (‘Kennmelder’) and insulated gripping lugs (‘Traggriff’) for safe handling.
