level.
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 altitude:

in the electrical 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 release or Ekip Dip release,
between -40 ° C and + 85 ° C.
• Circuit-breaker in the original packaging, with Ekip Touch protection release, between
-30°C and + 85°C.
NOTE: The storage conditions may differ from the usage conditions.
