Packaging of switchgear components

The following devices and materials have to be delivered separately packed with the switchgear independent from the kind
of transport:
• withdrawable air circuit breakers,
• withdrawable moulded case circuit breakers with a nominal current of more than 1000 A,
• transformers and reactors with a weight of more than 25 kg, in the case of floor mounted units of more than 100 kg,
• precision instruments of high value for measuring and indication,
• fluorescent tubes,
• modules with single phase control power transformers of more than 2 kg,
• spare withdrawable and P-/R-modules,
• top stripe holders,
• withdrawable modules with weight ≥ 30 kg,
• raised roof plates incl. mounting angles
• active/passive modules
• filter modules.
Stacking of active and passive modules is allowed up to two boxes.
If possible the original packaging material of the manufacturer should be reused for packaging.
Modules as spare parts or as supplementary parts for the switchgear shall be marked with the necessary technical data for
the use (module location, type, order number). The fuses remain in the modules. Information concerning the procurement of
standard boxes can be obtained from the ABB shipping department.
The quality of the internal packaging depends on the type of goods to be packaged and shall be selected by the ABB ship-
ping department.
Materials to be used:
Padding (chips made of expanded polystyrene), corrugated cardboard, foil, expanded polystyrene board, cardboards.
Any special shipping requirements of the switchgear shipment shall be specified in the ordering phase.

Handling of switchgear components

5.3.1

Circuit breaker

Circuit breaker shall be handled in the following way:
• Fixed circuit breaker shall be braced additionally.
• All withdrawable air circuit breakers and withdrawable moulded case circuit breaker with a weight ≥40 kg shall be removed
and packed separately.
• Heavy busbar constructions have to be supported during transport in an adequate way. It is necessary to attach a caution
label demanding the removal of the used transport fixing material during switchgear erection.
If possible the original packaging material should be reused for packing the circuit breaker.
The bracing shall be removed prior to commissioning.
Separately shipped circuit breakers are to be mounted in accordance with the mounting instructions enclosed.
5.3.2

Withdrawable modules

Withdrawable modules have to be secured for shipping by their own mechanical interIock operated by the switch handle
(ON, OFF or TEST position). In addition, the withdrawabIe modules may be secured by a latch-type lock which works inde-
pendently from the mechanical interlock and which may be operated by 5 mm double bit key or a cylinder type safety key.
!
Modules shall be secured with handles in the "OFF" position.
Necessary switch positions prior to commissioning: Module handle must be in position "OFF".
5.3.3

MNS-Up UPS modules

Active and passive MNS-Up modules must be removed from the MNS-Up section and packed in the original boxes before
shipping.
