## Long description

The Rittal PTC heater 3105.390 is a compact rack-mounted heating unit designed to maintain stable temperatures inside electrical enclosures and server racks. Measuring 103 mm x 103 mm x 200 mm, the device combines a PTC heating element with an integrated fan to provide forced-air circulation and controlled thermal output. It operates from a 230 V supply and is intended for continuous operation in environments where condensation prevention and temperature regulation are required.
Advantages
The heater delivers a continuous thermal output ranging from 235 W to 800 W, allowing for application in small to medium-sized racks. Its PTC (positive temperature coefficient) element provides self-regulating heating behavior, reducing the risk of overheating. The unit includes a single fan for improved air distribution and a quick-connect terminal for simplified installation and maintenance. The compact form factor and neutral black-and-grey color make it compatible with standard rack layouts and enclosure interiors.
Suitable for (tasks / use cases)
Preventing condensation and moisture build-up in electrical enclosures and control cabinets
Maintaining minimum operating temperature for sensitive electronic components in server and network racks
Temperature stabilization in outdoor or unheated cabinets where ambient temperature may fluctuate
Applications requiring reliable, continuous low- to mid-range heating with forced ventilation

How to use
Mount the heater inside the rack or enclosure in a position that allows free airflow and effective circulation throughout the cabinet. Connect the unit to a 230 V supply using the quick-connect terminal, following applicable electrical safety standards and ensuring proper earthing. Allow the integrated fan to run continuously with the heater powered to distribute warm air and prevent cold spots. Verify that the heater’s rated current (up to 6 A) is compatible with the enclosure’s power distribution and protective devices.
Usage recommendations
For reliable operation, install the heater in a location away from obstructions and maintain a clearance around the fan inlet and outlet. Regularly inspect connections and the fan for dust build-up and clean as needed. Use the heater primarily for temperature maintenance and condensation prevention rather than space heating; ensure protective devices and wiring are sized appropriately for the continuous thermal output.
