In the event that the fuse tripping fails, e.g. if the fuse has been inserted incorrectly, the fuse box is protected by thermal protection. The overpressure generated by overheating trips the switch via the diaphragm in the cover of the fuse box and via an articulation. This breaks the current before the fuse box incurs irreparable damage. The above thermal protection works independently of the type and design of the HV HRC fuse used. Like the fuse itself, it is maintenancefree and independent of any outside climatic effects. Furthermore, the Siemens HV HRC fuses release the striker pin independently of the temperature and trip the three-position switch-disconnector as early as in the fuse overload range. Impermissible heating of the fuse box can be avoided in this way.
