Storage, lifting and weights

Protected by an external wooden crate, the circuit breaker is fastened with screws to the pallet used for transport or to the bottom of the pack-
ing crate.
If the circuit breaker must be stored for even a short period of time before being put into service, after having been checked on receipt it must
be put back into its container and covered with a waterproof material.
Caution
– Store the circuit breaker in a dry, dust-free room well away from aggressive chemicals.
– Place the circuit breaker and any fi xed part on a horizontal surface, not in direct contact with the fl oor but on a suitable support (Fig. 4).
– The maximum number of circuit breakers that can be stacked on top of each other is shown in fi gure 5.
– Keep the circuit breaker in the open position with the closing springs unloaded to prevent unwarranted stress and the risk of accidents to the
personnel.
