Packing and transport
The circuit-breaker is shipped in special pack-
ing, in the open position and with the springs
discharged.
Each piece of apparatus is protected by a plas-
tic cover to prevent any infiltration of water dur-
ing the loading and unloading stages and to keep
the dust off during storage.

!
ways make sure that the operating

the nameplate data (see fig. 1) with what is speci-
fied in the order confirmation and in the accom-
panying shipping note.
