The TeSys D (LC1D) catalogue details the specifications for normal ambient temperature under AC1 duty.
In instances where the ambient temperature (surrounding the product, i.e. inside the enclosure) exceeds the limit quoted in the catalogue, then a derating of the continuous thermal current is applied;
Please consult table below:
Additional good practice measures when using contactors in high ambient;

Please consult table below:
Additional good practice measures when using contactors in high ambient;
- Avoid side by side (without air gap) mounting.
- Ensure good air circulation to avoid hot spots.
- Ensure cable sizes are conservative to ensure good heat sink properties.
