Technical Data

Standards, specifications, guidelines

Resistance to internal arc faults

• 1. Safety of operating personnel ensured by tests to verify resistance to internal arc faults.
• 2. Internal arc tests in accordance with IEC 62 271-200, Annex A.
• 3. The switchgear compiles with criteria 1 to 5 specified in the mentioned standards for the basic version up to 31.5 kA
• 4. Definitions of criteria:

– Criterion 1

• Correctly secured doors and covers do not open.Deformations are accepted conditionally.

– Criterion 2

• No fragmentation of enclosures occurs within the time specified for test. Projections of small parts up to 60g are accepted.

– Criterion 3

• Arcing does not cause holes in the accessible sides up to a height of 2m.

– Criterion 4

• Indicators do not ignite due to the effect of hot gases. Ignition caused by glowing particles rather than hot gases is allowed. Ignitions as a result of paint or sticker burning are also excluded.

– Criterion 5

• The enclosure remains connected to its earthing point.

Current-carrying capacity :

• 1. According to IEC 62 271-200 current-carrying capacities refer to the following ambient temperatures:
• – Maximum of 24-hour mean +350C
  – Maximum +400C


• 2. The current-carrying capacity of the panels and busbars depends on the ambient temperature outside the enclosure.


• 3. To attain the maximum rated normal currents, the panels may be provided with natural or forced ventilation.


• 4. Protection against solid foreign bodies, electric shock and ingress of water


• 5. 8Bk80 switchgear fulfills acc. to the standards
• -IEC 62 271-200
  -IEC 60 529.


• 6.The following degrees of Protection:
• - Enclosuer: IP4X
  - Compartments: IP2X
