Mode of operation
26
In the event that an HV HRC fuse-link has tripped, the switch is tripped via an articulation
which is integrated into the cover of the fuse box.
In the event that fuse tripping fails, e.g. if the fault current is less than I
has been inserted incorrectly, the fuse box is protected by thermal protection.
The overpressure generated by overheating trips the switch via a diaphragm in the cover
of the fuse box and via the articulation. This breaks the current before the fuse box
incurs irreparable damage. This thermal protection works independently of the type and
design of the HV HRC fuse used. Like the fuse itself, it is maintenance-free and
independent of any outside climatic effects.
