## Long description

The Rittal SK 3189.340 built-in cooling unit is designed for conditioned enclosures and electrical cabinets that require dependable thermal management. With a rated cooling capacity of 4900 W and a compact aluminium grey housing, the unit operates on 380–480 V at 50/60 Hz and includes an integrated display for status readout and basic control functions. The cooling unit is intended to mount into cabinet walls and supports continuous removal of heat from control panels, switchgear and other sensitive electronic equipment.
Advantages
The integrated display provides clear status information and simplifies on-site adjustments. A robust aluminium housing offers corrosion resistance and mechanical protection while keeping the unit lightweight for easier installation. The wide input voltage range (380–480 V) and support for both 50 and 60 Hz mains make the unit compatible with diverse industrial power systems. The 4900 W cooling capacity handles substantial heat loads typical in medium-to-large electrical cabinets.
Suitable for
 Air-conditioned electrical enclosures and switchgear in industrial environments
 Control panels with moderate to high internal heat dissipation
 Applications requiring wall-mounted or built-in cabinet cooling
 Sites with 380–480 V three-phase power at 50/60 Hz
When it may not be suitable
This cooling unit is intended for built-in cabinet installation and may not suit free-standing or portable cooling needs. It is designed for electrical enclosures and may be oversized for very small cabinets with minimal heat dissipation.
