Product Information
Full details
The Rittal 3105.400 is an enclosure heater designed for industrial applications to prevent damage caused by humidity and low temperatures within electrical enclosures. It regulates relative humidity, prevents temperatures from dropping below the dew point, and stops condensation, thereby protecting against corrosion and electrical short circuits. While effective, users should note its specific voltage requirement and thermal output when integrating into existing systems.

FAQs
What is the primary function of the Rittal 3105.400 heater?
Its primary function is to prevent condensation and humidity buildup inside electrical enclosures by maintaining the internal temperature above the dew point.
What is the power output of this heater?
The heater has a continuous thermal output of 870W.
Does this heater require a thermostat?
No, this PTC heater is self-regulating and does not require an external thermostat for basic operation. It adjusts its output based on its temperature.
What is the IP rating of the Rittal 3105.400?
The enclosure heater has an IP20 degree of protection.
Can this heater be used in any enclosure?
It is designed for use in electrical enclosures and is compatible with 230V AC. Its suitability depends on the enclosure size, ambient conditions, and the required thermal output. Ensure proper ventilation.
What are the dimensions of the heater?
The dimensions are 200mm (height) x 103mm (width) x 103mm (depth).
Is the fan always running?
The fan is typically integrated with the heating element and operates to distribute heat. Its speed may vary based on the PTC element's temperature.
Troubleshooting
Heater does not turn on.
Verify that the enclosure is supplied with 230V AC power and that the circuit breaker is engaged. Check all electrical connections to the quick-connect terminals for security.
Fan is not spinning.
Ensure power is supplied to the unit. If power is present and the fan still does not spin, the fan motor may require service or replacement.
Excessive condensation still present.
Confirm the heater's thermal output is sufficient for the enclosure size and ambient conditions. Check for air leaks or insufficient mounting height. Ensure the heater is not obstructed.
Heater is running continuously.
PTC heaters are designed to self-regulate. If the unit feels excessively hot or runs constantly without reaching ambient temperature, check for obstructions to airflow or potential damage to the PTC element.
Pros and Cons
Pros
- Effectively prevents condensation and humidity-related damage.
- Integrated fan ensures even heat distribution.
- Self-regulating PTC heating element enhances safety and efficiency.
- Compact design with dimensions of 200mm x 103mm x 103mm.
- IP20 protection rating suitable for many industrial environments.
Cons
- Fixed thermal output of 870W may be too high for smaller enclosures or specific applications.
- Requires a 230V AC power supply, limiting compatibility with different voltage systems.
- Plastic material might have limitations in extremely high-temperature or corrosive environments.
- Not suitable for applications requiring precise temperature control beyond dew point prevention.
Setup, Compatibility & Care
Setup:
- Mounting: Securely mount the heater vertically within the enclosure using appropriate mounting points. Ensure adequate airflow around the unit.
- Wiring: Connect the heater to a 230V AC power source using the provided quick-connect terminals. Ensure all connections are secure and compliant with local electrical codes.
- Placement: Position the heater low within the enclosure to allow warm air to rise and circulate naturally, aided by the fan.
Compatibility:
- Voltage: Compatible with 230V AC power supplies (50-60 Hz).
- Environment: Suitable for use in environments where ambient temperatures are not excessively high, as it is designed to heat, not cool. The IP20 rating means it is protected against solid objects greater than 12.5mm but not against water ingress.
- Enclosure Size: The 870W output is best suited for medium to large enclosures where significant temperature regulation is required.
Care:
- Cleaning: Disconnect power before cleaning. Use a dry or slightly damp cloth to wipe down the exterior and fan grille. Avoid using abrasive cleaners or solvents.
- Inspection: Periodically inspect the heater and fan for dust buildup or obstructions. Ensure ventilation slots are clear.
- Maintenance: The fan and heating element are generally maintenance-free, but regular visual checks are recommended.
