## Summary description

Rittal 3105.410 is a PTC heater designed as a rack/cabinet accessory with a single built-in fan. It provides cabinet heating and air circulation to prevent condensation and maintain stable internal temperatures. The unit is finished in black and grey and supplied as a single piece, suitable for electrical enclosures and control cabinets.

## Long description

Rittal 3105.410 is a PTC heater with an integrated fan designed for use in racks and electrical enclosures. The unit combines a positive temperature coefficient heating element with a single built-in fan to deliver controlled cabinet heating and air circulation. Finished in black and grey, this accessory is intended to reduce relative humidity, prevent condensation and maintain stable internal temperatures in control cabinets and switchgear housings.
Advantages
The PTC heating element provides self-regulating temperature behaviour, reducing the risk of overheating while maintaining consistent heat output. The built-in fan improves air circulation within the enclosure to distribute heat evenly and accelerate moisture removal. The compact design allows installation in racks and cabinets where space is limited, and the two-colour finish integrates with common enclosure aesthetics. Continuous thermal output range supports maintaining temperatures above the dew point to prevent condensation-related damage.
Suitable for (tasks / use cases)
 Maintaining internal temperatures in electrical enclosures and control cabinets
 Preventing condensation and reducing humidity inside racks
 Protecting sensitive electronics from corrosion and short-circuits caused by moisture
 Small- to medium-sized cabinets where a single-fan heater is sufficient
When it may not be suitable
This heater is intended for use in enclosed racks and cabinets and may not be suitable for open or poorly sealed enclosures where heat loss is high. For very large cabinets or rooms that require higher total heating capacity, multiple units or a different heating solution may be necessary. Do not use the unit outside of the recommended enclosure application or in locations with incompatible ambient conditions.
Key specifications
 Heater type: PTC (positive temperature coefficient) with self-regulating behaviour
 Airflow: single built-in fan for internal circulation
 Colour: black and grey finish
 Application: rack and electrical enclosure heating to prevent condensation
 Continuous thermal output range: 235 – 800 W (application-dependent)
 Supply: mains AC (single-phase) at rated voltage per product configuration
 Mounting: designed for installation in control cabinets and racks
How to use
Mount the heater in the designated position inside the cabinet or rack following the enclosure manufacturer's mounting points and safety clearances. Connect the unit to the appropriate mains supply and any required control or thermostat wiring according to local electrical codes and the product's installation instructions. Adjust the heater and fan settings, where applicable, to maintain a temperature above the dew point but within equipment operating limits. Regularly inspect the device and the cabinet interior for dust buildup and ensure ventilation paths remain unobstructed.
What to consider before purchase
 Cabinet size and required heating output to ensure the heater's continuous thermal range is sufficient
 Compatibility with the cabinet's mounting options and available space for a single-fan unit
 Mains voltage and electrical connection requirements for the chosen configuration
 Environmental conditions inside the enclosure, including allowable temperature range and ingress protection needs
Usage recommendations
Use the Rittal PTC heater in sealed or moderately ventilated cabinets where preventing condensation and stabilising internal temperature are priorities. For optimal performance, combine the heater with a thermostat or hygrostat to control runtime and maintain target humidity levels; consider additional units for larger enclosures or higher heat-loss situations.
