## Summary description

Rittal 3366.545 is an industrial rack cooling unit with a built-in display, designed for enclosure temperature control. It provides a maximum cooling capacity of 4000 W and operates on 400/460 V, 50/60 Hz with a nominal current of 1.9 A. Constructed of steel/stainless steel and finished in grey, it suits server racks and electrical cabinets requiring powerful active cooling.

## Long description

Rittal 3366.545 is a rack cooling unit with a built-in display designed for active temperature control inside server racks and electrical enclosures. The unit delivers up to 4000 W of cooling capacity and operates on 400/460 V at 50/60 Hz, offering robust performance for heat-sensitive components. Constructed from steel and stainless steel with a grey finish, it is intended for wall- or rack-mounted installation where concentrated cooling and reliable control are required.
Advantages
This cooling unit provides high cooling capacity suitable for demanding enclosures while maintaining energy-efficient operation in its class. The integrated display simplifies monitoring and adjustment of setpoints and operating modes. Built with corrosion-resistant materials and designed for industrial environments, the unit supports continuous operation and stable temperature regulation. Compatibility with Blue e system characteristics allows integration into standardized cooling families for uniform maintenance and parts handling.
Suitable for
 Server racks and data cabinets that require up to 4000 W of active cooling
 Electrical control cabinets and switchgear with concentrated heat loads
 Industrial environments where a wall- or rack-mounted cooling solution is needed
 Applications needing a visible, built-in display for local monitoring and control
When it may not be suitable
This unit is designed for fixed electrical installations and requires a 400/460 V, 50/60 Hz supply; it is not suitable where only low-voltage single-phase supplies are available. For very small enclosures or locations with minimal heat dissipation needs, the 4000 W capacity may be excessive both in size and energy use.
Key specifications
 Cooling capacity: up to 4000 W
 Supply voltage: 400/460 V (three-phase), 50/60 Hz
 Nominal current: 1.9 A
 Construction materials: steel / stainless steel
 Finish: grey
 Mounting: rack or wall-mounted format
 Integrated user display for local monitoring and control
 Energy-efficient design; includes electrical condensate evaporator in higher output ranges
How to use
Install the cooling unit in accordance with manufacturer mounting guidelines for rack or wall application, ensuring correct airflow paths and sufficient clearance. Connect to the specified 400/460 V, 50/60 Hz supply and configure the built-in display to set desired temperature setpoints and operating modes. Regularly check condensate handling and service access points; for models with an electrical condensate evaporator verify operation during commissioning. Follow site safety procedures and ensure earthing and electrical protection are provided by a qualified technician.
What to consider before purchase
 Verify available supply voltage and electrical infrastructure (400/460 V, 50/60 Hz)
 Confirm enclosure dimensions and mounting type (wall or rack) to ensure fit and correct airflow
 Assess required cooling capacity versus typical heat load to avoid oversizing
 Plan for condensate management and maintenance access
Usage recommendations
For reliable operation, match the unit's 4000 W capacity to measured enclosure heat loads, maintain clear intake and exhaust paths, and schedule periodic inspections of filters and condensate systems. Consider integration with Blue e IoT interfaces or building management systems where remote monitoring and analytics are required.
