DIN - Fuse Links
Fuse Links comply with DIN dimensional
standard DIN43625.
‘F’ range, high performance full range fuse link.
‘S’ range, high performance back-up fuse
link, with striker tripping.
‘A’ range, including high current rating
back-up fuse link.
Comply with IEC 60282-1 and VDE 0670 part 4.
Wide variety of ratings, 3.6 kV to 36 kV.
Versions suitable for indoor and outdoor use.
Motor circuit fuse link option.
Bussmann DIN ‘S’ Fuse Links
The time current characteristics of the ‘S’ range is optimised to ensure improved discrimination with upstream devices
and to give fast clearance of earth faults in the secondary terminal zones. The breaking performance with low over
currents is adequate to cater for all normal distribution applications, where low voltage fuse links on the secondary side
take care of low overload faults, leaving the high voltage fuse links to clear major faults ahead of LV protection. The fuse
links are suitable for use even where there is no secondary LV protection, provided that they are used in fuse switches
fitted with instantaneous striker tripping.
Bussmann DIN ‘F’ Fuse Links
The ‘F’ range fuse links have ‘full range’ clearing capability. Bussmann ‘F’ types are designed to clear all overloads right
down to fuse’s rated current in accordance with latest IEC 282-1 requirements. They are thus suitable for use as a sole
form of protection. ‘F’ range time current characteristics are especially advantageous for transformer protection
applications.
Bussmann DIN ‘A’ Fuse Links
This earlier, well proven design, has values of minimum breaking current between the ‘S’ and ‘F’ range including higher
current ratings.

Notes
a)
b)
17.5kV fuse links in 10/12 dimensions are offered, since some
switchgear in the 10/12 series is suitable for use at higher voltages.
Fuse links listed are normally for indoor use but versions suitable
for outdoor use are olso available in the same ratings and
dimensions. For outdoor versions of the ‘S’ range, replace the ‘S’
with a ‘T’ when ordering - for example ‘TDLSJ’
c)
* All the fuse link code references listed in the proceeding tables
are for striker fitted versions, for non-striker versions please
replace the letter ‘S’ with the letter ‘N’ in the code - for example
‘SDLNJ’. For further information on our parts referencing system,
please refer to section 10 of this catalogue.
