Ö Pull the HV HRC (current limiting) fuse towards the front of the panel to release the
fuse from the fuse clips.
The HV HRC (current limiting) fuse has been removed.
25.3 Checking the fuse tripping mechanism
When first placing the SIMOSEC switchgear into service and before installing
replacement HV HRC (current limiting) fuse, check the tripping behavior of the switch-
disconnector in all three phases, preferably by means of test fuses.
To check the fuse tripping mechanism on switchgear connected to the power system,
the panel to be tested must be isolated and grounded, including the bus bars.
