Parking position
For maintenance, e.g. of 1-pole switchable in-line fuse switch disconnectors – sizes 1 to 3 – and for 3-pole switchable in-line fuse switch disconnectors – size 00 – the fuse carriers can be mounted after being turned by 180° (fuse facing outwards).
This results in the following advantages:
-
Visible disconnection point
-
Depot for fuse links (parking position)
-
No opportunity for mistakes when replacing the fuse links
-
Additional touch protection in the vicinity of the lyre-shaped contacts
