Technical information
Protective treatment of equipment
according to climate
“TH” treatment for hot and humid environments
This treatment is suitable for hot and humid atmospheres where installations are
regularly subject to condensation, dripping water, and the risk of fungi.
In addition, the plastic insulating components are resistant to attacks from insects
such as termites and cockroaches. These properties have often led to this treatment
being described as “Tropical Finish,” but this does not mean that all equipment
installed in tropical and equatorial regions must systematically have undergone “TH”
treatment. Conversely, certain operating conditions in temperate climates may
require the use of “TH” treated equipment (see limitations for use of “TC” treatment).
Special characteristics of “TH” treatment
b All insulating components are made of materials which are either resistant to fungi
or treated with a fungicide, and which have increased resistance to creepage
(Standards IEC60112, NF C 26-220, DIN5348).
b Metal enclosures receive a top-coat of heat-treated, fungicidal paint, applied over
a rust inhibiting undercoat. Components with a “TH” treatment may be subject to a
surcharge; please consult your local sales office. (A large number of the
Telemecanique brand products are “TH” treated as standard, so they are not subject
to a surcharge.)
Protective treatment selection guide
Indoors
Outdoors (sheltered)
These treatments cover, in particular, the applications defined by methods I and II of
guide UTE C 63-100.
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
type CCX controllers, and flush-mountable type XBT operator terminals) require the
use of an enclosure providing a degree of protection to at least IP54, as defined by
standards IEC 60664 and NF C 20 040, for use in industrial applications or in
environmental conditions requiring “TH” treatment.
These electronic products, including flush-mountable products, must have a degree
of protection to at least IP20 (provided either by their own enclosure or by their
installation method) for restricted access locations where the degree of pollution
does not exceed 2 (for example, a test booth not containing machinery or other dust-
producing activities).
Special treatments
For particularly harsh industrial environments, Schneider Electric is able to offer
special protective treatments. Please consult your local sales office.
