1. Description
1.1 General
characteristics
Tmax T8 circuit-breakers and disconnectors consist of a plastic structure which houses the operating mechanism, the poles and the auxiliary
parts. Each pole is insulated from the others and contains the circuit breaking parts and the current sensor of the corresponding phase.
The fi xed version circuit-breaker has its own terminals for connection to the power circuit.

Checking on receipt
Examine the condition of the material received and make sure that it corresponds to what was ordered. Any damage or non-compliance found
when the material has been unpacked, which must be carried out with due care, must be notifi ed within 5 days of receipt and the number of the
shipping notice must be indicated on the notifi cation.
3.
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 its back into its container and covered with a waterproof tarpaulin.
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.
