SIVACON is resistant
to internal arcing faults
10
Testing of low voltage switchboards under internal
arcing fault conditions is classified as a special
test in accordance with IEC 61641 or VDE 0660
Part 500, supplement 2.
This test serves to gauge the dangers to which
persons might be exposed in the event of an internal
arcing fault.
By way of the test under internal arcing fault
conditions, SIVACON provides evidence of personnel
safety in terms of the following assessment criteria
as standard:
Arc barrier
Assessment criteria
1. Doors, covers etc. must not
open
2. No parts may fly off
3. No holes may be burnt into
the enclosure
4. Indicators must not ignite
5. The protective conductor
circuit for touchable parts
of the enclosure must still
be in working order
Additional modules for limiting
the effects of the arcing fault
inside the switchboard
• Restriction to one cubicle
(Arc barrier)
• Restriction to the function
compartment or place of
origin
• Insulated main busbars
(design without base)
