9.9 Replacing HV HRC fuse-links
NOTICE
Unsuitable HV HRC fuse-links or extension tubes
Using untested or incorrect HV HRC fuse-links can damage the fuse box.
⇨ Use only fuse-links tested by Siemens, which are listed in the fuse protection table.
⇨ Do not use HV HRC fuse-links with different characteristics for nominally equal rated
current.
⇨ Any use of other fuse-links must be checked by Siemens in advance. Contact the
Siemens Service Hotline.
NOTICE
Stressed HV HRC fuse-links
When a HV HRC fuse-link has tripped, the HV HRC fuse-links in the two other phases may
also have been stressed.
⇨ Replace the HV HRC fuse-links in all 3 phases.
INFORMATION
Not approved fuse-links for switchgear with a rated voltage of up to 12 kV:
▪ 7.2 kV fuse-links with reference dimension 192 mm
▪ 24 kV fuse-links with reference dimension 292 mm
Observe the design of the fuse slide supplied (reference dimension e=292 mm, optionally
e=442 mm)
