Panel weights
800-1250 A versions : from approx. 550 kg up to
approx. 1000 kg
...2500 A versions : up to 1650 kg
Weights depend on version, design, and equipment
2.4 Internal arc classification
Internal arc classification (AFLR)
Circuit breaker/busbar compartment
Cable compartment
•
When plasma diverters are used (standard),
thearc gases are conducted to the rear
-
Panel by panel for the circuit-breaker
compartment, and
-
Centrally via a pressure relief duct (F), (see
page 9 ), from the busbar compartments to a
metering panel or sectionalizerpanel. If the
installation does not contain a metering panel
or sectionalizer panel, anoutgoing feeder
panel can be used for pressure relief
Panel width
• The panels can have optionally integrated
500/800 mm
pressure relief ducts with the opportunity for
31.5 kA, 1 s
- Conducting out of the switchroom in a manner
31.5 kA, 1 s
suitable for the building dimensions, or
- Conducting through an absorber on the last
two panels (when the ceiling height is
sufficient)
• In the case of an arc fault, an increase of
pressure in the switchroom is to be expected.
This is to be taken into account in the planning.
Calculations can be supplied on request
