ATHF heaters are used to maintain a microclimate inside control and automation cabinets. The installation of ATHF heaters helps to protect the installed electrical equipment against the effects of low temperatures, moisture and dew.
ATHF heaters consist of an enclosure, a posistor heating element, and a terminal block. The enclosure is equipped with a DIN rail mounting bracket.
For optimum use the ATHF heaters should be mounted vertically in the enclosure, leaving space above and below the heater. Thermostats and gyrostats are recommended for regulating the climate and controlling the ATHF heaters.
