## Summary description

Rittal SK 3189.945 is a built-in cooling unit designed for electrical enclosures, with an input power of 5500 W and input voltage range 380–480 V at 50/60 Hz. The unit features a steel grey housing and provides reliable climate control for control cabinets, switchgear and industrial panels where active cooling is required.

## Long description

The Rittal SK 3189.945 is a built-in cooling unit engineered for electrical enclosures and control cabinets that require active temperature control. With a nominal cooling capacity of 5500 W and compatibility with a 380–480 V, 50/60 Hz supply, this grey steel-housed unit is intended to maintain stable internal temperatures in switchgear, control panels and industrial electronics installations where heat extraction is necessary.
Advantages
This cooling unit provides high continuous cooling power suited to demanding environments and is designed for integration into enclosure walls to save interior space. The steel housing offers mechanical robustness and long service life in industrial conditions. The unit supports both 50 Hz and 60 Hz networks across a wide voltage range, simplifying electrical compatibility in multi-region applications.
Suitable for
Control cabinets and switchgear with high heat dissipation
Industrial automation panels and drive cabinets
Enclosures housing power electronics, converters and PLCs
Sites requiring wall-mounted, built-in cooling solutions
When it may not be suitable
This built-in cooling unit is intended for electrical enclosures and may not be suitable for general room air conditioning or applications that require portable or floor-standing refrigeration. It is designed for systems with three-phase supply voltages in the 380–480 V range; installations with significantly different power or voltage requirements will need a different model.
Key specifications
Cooling capacity: 5500 W (nominal)
Supply voltage range: 380–480 V
Supply frequency: 50/60 Hz
Mounting type: built-in / wall-mounted for enclosures
Housing material and color: steel, grey
How to use
Install the cooling unit into the prepared cutout in the enclosure wall following enclosure manufacturer guidelines and local electrical codes. Connect the unit to the appropriate three-phase power supply within the specified voltage and frequency range, ensuring correct protective devices and grounding are in place. Configure any available control or alarm interfaces according to the enclosure cooling strategy, and verify airflow paths and filter condition to maintain efficient heat extraction.
What to consider before purchase
Confirm the enclosure cutout dimensions and clearances for a built-in mounting unit
Verify that the supply voltage and frequency at the installation site fall within the 380–480 V, 50/60 Hz range
Ensure the unit's cooling capacity (5500 W) matches or exceeds the enclosure heat load
Check compatibility with the enclosure's ingress protection and airflow arrangement
Usage recommendations
For reliable operation, schedule regular inspection of air filters and pollutant traps, verify electrical connections and protective devices, and maintain unobstructed airflow through the enclosure. Use the unit as part of an overall thermal management plan that includes component placement and ventilation to optimize cooling performance and extend equipment life.
