FAQs

What is the primary function of the Rittal SK 3105.370?

Its primary function is to heat the inside of electrical enclosures to prevent condensation and maintain a temperature above the dew point, thus protecting components from moisture damage and corrosion.

What voltage ranges does this heater support?

It supports AC operating voltages from 110 to 240V at 50/60 Hz and DC operating voltage of 110V.

How is the heater mounted?

The heater is designed for internal mounting within an enclosure, typically using DIN rail or direct mounting methods. Specific mounting hardware may vary and should be secured according to standard industrial practices.

What is the IP rating of this enclosure heater?

The product description indicates an 'Other' degree of protection (IP), suggesting it's designed for internal enclosure use where protection is provided by the enclosure itself. Specific IP rating should be confirmed with Rittal documentation.

Can this heater be used in any enclosure?

It is suitable for most standard industrial enclosures where its compact dimensions can be accommodated. Ensure sufficient clearance for heat dissipation and electrical connections.

Does the heater have an integrated thermostat?

The product description does not specify an integrated thermostat. For temperature control, it is typically used in conjunction with an external thermostat or connected directly to power, relying on the enclosure's thermal mass and ambient conditions.

What are the physical dimensions of the heater?

The dimensions are 90mm in width, 75mm in depth, and 180mm in height.

Troubleshooting

Heater not turning on

Verify that the enclosure is connected to a live power source within the specified voltage range (110-240V AC or 110V DC). Check all electrical connections for security and proper wiring.

Enclosure still shows signs of condensation

Ensure the heater is correctly sized for the enclosure volume and the ambient conditions. Check if the heater is receiving power and if the thermostat (if applicable and separate) is set correctly. Confirm that the enclosure itself is properly sealed.

Overheating within the enclosure

Ensure the heater is not undersized for the enclosure or that the ambient temperature is not excessively high. Verify that there is adequate airflow around the heater and within the enclosure as per installation guidelines.

Pros and Cons

Pros
