In order to make the correct choice of protective treatment, two points should be remembered:
TH Treatment — Standard Treatment
The TeSys and K-Line relay are TH treated as standard, and because of this can be used in particularly severe conditions such as:
Insulating parts use plastic materials which resist attack from insects (termites, beetles…).
These qualities have led to this treatment being called Tropical Finish.
Characteristics
Steel parts are usually chrome galvanized or chrome galvanized or chrome cadmium plated; when the item has a mechanical function it can also be
painted.
Parts with an insulating function are manufactured in a material with improved leakage resistance, (standards IEC 112, NFC 26-220, DIN 53480) and are
treated to be fungus resistant.
Metallic enclosures are given a baked enamel finish, applied over a protective phosphatizing coat.
TH treatment is suitable for the most severe climatic conditions and conforms to the following standards:
UTE Publication C 63-100 (treatment II)
12 successive humid heat cycles at:
Standards DIN 50015-50016, alternating environmental chamber conditions:
Utilization Limits
TH treatment can be used in the following temperature and humidity conditions:
Temperature from +20 to +40°C / +68 to +104°F with a relative humidity which can reach 95%.
1. The prevailing climate of the country is never the only criterion.
2. Only the ambient conditions in the immediate vicinity of the equipment need be considered.
– hot and humid atmospheres with prevailing heavy condensation,
– dripping water and fungi.
+40°C / 104°F temperature and 95% relative humidity
+48 hours of salt spray.
+23°C / 73°F temperature and 83% relative humidity
+40°C / 104°F temperature and 92% relative humidity.
