Once this altitude is passed, you need to consider reduction of dielectric strength and reduced cooling
capacity of the air.
The following are the corrections expressed as a percentage to be applied to the parameters according to

system.
The SACE Emax 2 circuit-breakers were developed and tested in an EMC environment in accordance with
IEC 60947-2, Annex J and F.
The storage ambient temperature must be:
• Circuit-breaker in the original packaging, without protection trip unit or Ekip Dip trip unit, between -40°C
and +85°C, -40°F e +185°F.
• Circuit-breaker in the original packaging, with Ekip Touch protection trip unit, between -25°C and + 85°C,
-22°F e +185°F.
NOTE: the storage conditions may differ from the usage conditions.
