10 Appendix A Fuse base tables
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

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)!
Fuse-link
gL = Whole area line protection (obsolete designation)
gG = Whole area appliance protection (obsolete designation)
gL-gG = Cable and line protection, discriminating characteristics
Circuit-breaker type
B = Area of instantaneous tripping 3 - 5 x I
N
C = Area of instantaneous tripping 5 - 10 x I
N
K = Area of instantaneous tripping 8 - 15 x I
N
D = Area of instantaneous tripping 10 - 20 x I
