Low-voltage fuses (fuse-links) acc. to DIN EN 60269. VDE 0636 (e.g. l.v. h.b.c.) and circuit-brea-
kers acc. to DIN EN 60898. VDE 0641
Melting times or trip-out time are depending on current-time characteristics and trip-out current

Fuse links are classified in utilisation categories (e.g. gL-gG)
Circuit-breakers were formerly characterised with a letter, today, the same letter is also the type
designation
The current-time characteristics (see data in the fuse base table below) are identical for fuse type
NV and gG (indicated in display) and gL-gG (entry in table)!
