What is the temperature derating specification for a SM6 cubicle with ambient temperature.

 For an ambient temperature between 40°C and 60°C, we must proceed to a deration on nominal current.
This rule is not available for fuse combination units.

The rule is: it is necessary to decrease the current of 1% per degree higher than 40°C.

Example, for an ambient temperature of 50°, it is necessary to restrict the current in the cell with 90% of its rated current
