Overview
Fuse terminals are used to protect control circuits against
short-circuit.
The fuse terminals are intended for 5 mm × 20 mm and
5 mm × 25 mm G fuse links up to 6.3 A and 250 V and for bridg-
ing links up to 16 A and 800 V and have a mounting for a replace-
ment fuse link.
Fuse terminals are positive opening fuse-disconnectors.
The fuse links must be replaced at zero voltage.
Finger safety is ensured in both closed and open positions.
The LED indicates the status of the disconnected fuse (residual
current from 2 to 5 mA), but not if the plug is removed (floating).
The fixing base of the terminal allows both centered and re-
cessed mounting, allowing the unhindered routing of a
10 mm x 3 mm copper busbar. The fuse terminal can therefore
be combined with other terminals of a branch to form a group.
