Product Information
Full details
The Rittal SK Heating Element (3105390) is designed for industrial enclosures to regulate relative humidity and prevent condensation, thereby avoiding damage from corrosion or electrical short circuits. It is ideal for users who need reliable environmental control within sensitive electrical cabinets. A potential limitation is its fixed thermal output of 415W, which may not suit all enclosure sizes or ambient temperature variations without careful consideration. Key features include a built-in fan for even air distribution and a PTC heating element for efficient operation.

Extended Product Information
FAQs
What is the primary function of this Rittal SK heating element?
The primary function is to regulate relative humidity and prevent condensation inside electrical enclosures, thereby preventing corrosion and electrical short circuits.
What is the thermal output of this heater?
The thermal output of this heater is 415W.
What voltage does the heater require?
The heater requires an operating voltage of AC 230V.
Does this heater have a fan?
Yes, it features a built-in fan to ensure uniform air distribution within the enclosure.
What are the dimensions of the Rittal 3105390 heater?
The dimensions are 200mm in height, 103mm in width, and 103mm in depth.
What is the degree of protection for this enclosure heater?
The degree of protection is IP20.
How should I clean the heating element?
Clean the exterior with a dry or slightly damp cloth. Avoid abrasive cleaners and ensure the unit is powered off and cool before cleaning.
Can this heater be used in outdoor enclosures?
While it helps control internal conditions, its IP20 rating means the *enclosure itself* must provide adequate protection against external environmental factors like dust and water.
Troubleshooting
Heater not turning on
Verify the AC 230V power supply is connected correctly and is active. Check the circuit breaker or fuse for the power source. Ensure the connection to the quick-connect terminals is secure.
Fan not spinning
Check for any obstructions preventing the fan from rotating. Ensure the unit is receiving power. If the fan remains non-operational, the unit may need replacement.
Excessive condensation still present
Confirm the heater is rated appropriately for the enclosure size and ambient conditions. Ensure the enclosure's seals are intact and the door is closed properly. Check if the 415W output is sufficient for the specific thermal load and humidity level.
Overheating within the enclosure
Ensure the heater is not oversized for the enclosure or ambient conditions. Verify the fan is operating correctly to distribute heat. Consider if external heat sources are contributing to the high temperature.
Pros and Cons
Pros
- Effectively prevents condensation and its associated risks.
- Integrated fan ensures even temperature and humidity distribution.
- Compact and easy to install in most enclosures.
- Reliable operation with PTC heating technology.
- Protects valuable electrical equipment from moisture damage.
Cons
- Fixed thermal output of 415W may not be suitable for all enclosure sizes or extreme conditions.
- IP20 protection rating means it is not suitable for extremely dusty or wet environments without additional enclosure protection.
- Requires a 230V AC power supply, limiting placement options.
- Fan noise, while generally low, may be a consideration in very quiet operating environments.
Setup, Compatibility & Care
Setup:
- Ensure the enclosure is clean and dry.
- Mount the heater vertically using the provided mounting points. The fan should be positioned to promote airflow within the enclosure.
- Connect the heater to a suitable AC 230V power source via the quick-connect terminals.
- Ensure the enclosure door seals properly to maintain the controlled environment.
Compatibility:
- Voltage: Requires AC 230V input.
- Enclosure Size: Suitable for enclosures where a 415W heater is appropriate for the ambient conditions.
- Environment: Designed for industrial environments; ensure the enclosure's IP rating is sufficient for the surrounding conditions.
Care:
- Periodically inspect the heater and fan for dust or debris buildup.
- Clean the exterior of the heater with a dry or slightly damp cloth. Avoid abrasive cleaners.
- Check the fan for obstructions and ensure it spins freely. Do not attempt to lubricate the fan motor, as it is typically sealed.
