1. Packing and transport

The circuit-breaker is shipped in special packing in the open
position, with the springs discharged and with the absolute

Each piece of apparatus is protected by a plastic cover to
prevent water from infiltrating during the loading and unloading
stages and to keep the dust off during storage.
