As a thermal link (TL) in electrical appliances and equipment, electrical plant and machinery. They react to ambient temperature and are, under certain conditions, sensitive to current at rated levels. Self-heating by current passing through the thermal link must be taken into consideration. Thermal links with forced air cooling are suited for higher current ratings. Please ask. To avoid possible damage of the thermal link, it is advisable to use sealing resins, impregnation fluids or cleaning solvents only after having consulted the manufacturer.
