“TH” Treatment for Hot and Humid Environments
This treatment is for hot and humid atmospheres where installations are subject to condensation,
dripping water, and the risk of fungi.
Plastic insulating components are also resistant to attacks from insects such as termites and
cockroaches. These properties have led to this treatment being described as “Tropical Finish,” but this
does not mean that all equipment installed in tropical and equatorial regions must have undergone “TH”
treatment. On the other hand, certain operating conditions in temperate climates may well require the
use of “TH”-treated equipment (see the Limits for Use of “TC” Treatment section on page 10).
The following are special characteristics of “TH” treatment:
• All insulating components are made of materials which are either resistant to fungi or treated with a
• Metal enclosures receive a top-coat of baked, fungicidal paint, applied over a rust inhibiting
Special Precautions for Electronic Equipment
Electronic products always meet the requirements of “TC” treatment. A number of them are “TH”-treated
as standard.
Some electronic products (for example, programmable controllers, flush-mountable controllers CCX,
and flush-mountable operator terminals XBT) necessitate the use of an enclosure providing a degree of
protection to at least IP 54 (as defined by the standards IEC 60664 and NF C 20 040) for use in industrial
applications or in environmental conditions requiring a “TH” treatment.
These electronic products, including flush-mountable products, must have a degree of protection to at
least IP 20 (either provided by the enclosure itself or following installation) for restricted access locations
where the degree of pollution does not exceed 2 (a test booth not containing machinery or other dust
producing activities, for example).

Telemecanique products are “TH” treated as standard and are, therefore, not subject to a price
surcharge). Please consult our local representatives or agents.
