Overview
Fuse terminals for blade-type fuses
The fuse terminals for blade-type fuses use blade-type fuses to
ISO/DIS 8820 / DIN 72581-3 as fuse elements. Terminals with
LED display are available for fast fault diagnosis "at a glance".
Fuse terminals for G fuse links
Fuse terminals perform two important tasks in connected electri-
cal systems. Firstly, they act as a fuse carrier and, secondly, as
a potential distributor.
The full-length bridge slot enables uninterrupted linking between
the through-type terminals and the fuse terminals.
Fuse terminals for G fuse links are available for standardized
electrical fuse formats 5 x 20 mm and 6.3 x 32 mm (inch fuse) -
and are optionally available with LED display to signal a blown
fuse.

Technical specifications
1)
Please note: G fuse holders must be selected according to the max. power loss (heat dissipation) of the G fuse links. Depending on the application and
installation method, the heating conditions must be tested in enclosed fuse holders. Higher ambient temperatures add to the load of the fuse links. so that the
offset of the rated current must also be taken into account. When selecting G fuse links, make sure that they do not exceed the specified maximum power
loss. For specification details, contact the fuse manufacturer.
