## Summary description

Rittal SK 3188.945 is a built-in cooling unit for electrical enclosures with 4000 W input power. It operates on 380–480 V and 50/60 Hz and features a grey steel housing. Designed to maintain safe internal temperatures in control cabinets and industrial racks, it is suitable for ventilation and heat removal in electrical and automation systems.

## Long description

The Rittal SK 3188.945 built-in cooling unit is designed for integration into electrical enclosures and control cabinets to maintain safe operating temperatures. With a nominal cooling capacity of 4000 W and compatibility with 380–480 V, 50/60 Hz supplies, this unit provides continuous thermal management for industrial automation, switchgear and electronic modules. The grey steel housing offers mechanical protection and is intended for flush or recessed installation in cabinet walls where space and reliability are priorities.
Advantages
The cooling unit delivers a high cooling power suitable for dense electronic assemblies and power distribution equipment while operating on common three-phase voltage ranges. Its steel enclosure provides durable protection against mechanical stress and supports straightforward integration into standard cabinet designs. The unit is built for continuous operation and assists in preventing overheating-related failures, helping to stabilize component life and performance in demanding industrial environments.
Suitable for
Control cabinets and electrical enclosures with moderate to high internal heat loads
Automation cabinets housing PLCs, drives and power electronics
Switchgear and distribution racks where temperature control is required
Industrial environments requiring recessed or built-in cooling solutions
When it may not be suitable
This built-in cooling unit is intended for installation into enclosures designed to accept recessed cooling modules; it may not be appropriate for free-standing room cooling or for enclosures without provision for built-in units. Applications that require very low-temperature control, specialised refrigerants, or explosion-proof certification should be evaluated separately, as the unit is specified for standard industrial environments and typical ambient conditions.
Key specifications
Cooling capacity: 4000 W (nominal)
Supply voltage: compatible with 380–480 V, 50/60 Hz
Mounting type: built-in / recessed installation for cabinet walls
Housing material and finish: steel with grey coating
Application: cooling and ventilation for electrical enclosures and control cabinets
How to use
Install the unit in a prepared cut-out in the cabinet wall following the enclosure manufacturer’s mounting instructions and local electrical codes. Connect the unit to the appropriate three-phase supply within the specified voltage range and ensure correct grounding. Provide adequate airflow paths for intake and exhaust and verify that enclosure seals and cable entries maintain the required protection rating. Commission the system by measuring inlet and outlet temperatures and adjusting any built-in controls or external thermostats to achieve the desired internal temperature setpoint.
What to consider before purchase
Confirm cabinet cut-out dimensions and compatibility with built-in mounting
Verify supply voltage and electrical connection requirements on site
Check required cooling capacity against the enclosure’s heat load calculations
Ensure ambient conditions and ingress protection ratings match the installation environment
Usage recommendations
For best performance, size the cooling capacity to exceed the expected heat load with margin, maintain regular filter and condenser cleaning intervals, and verify electrical connections and protective devices are correctly rated for continuous operation.
