Issue:
What are the temperature deratings for the LUB starters?

Product Line:
Operating Mechanism and Disconnect Switches

Environment:
North American Products

Cause:
​Would like to use the TeSys U above or below rated temperatures

Resolution:
We can commit only on the ambient temperature for operation and storage written in the catalogue.

The limitation is due to the use of electronic components in control unit, as exemple maximum  ambient temperature is different between LUCM (+60°C) or advanced control unit (+70°C).
Outside of the -25°C to +70°C range, we can not have a derating as the control unit may not operate properly and could be in internal fault.
