Cooling Unit Rittal SK 3305544 1150 W input, 1610 W cooling capacity, built-in display, steel housing, 400/460 V 50/60 Hz

The Rittal cooling unit SK 3305544 is a wall-mounted enclosure cooler designed for industrial cabinets and electrical enclosures. With an input power of 1150 W and a maximum cooling capacity of 1610 W, it provides controlled temperature management for installations requiring reliable heat removal. The unit features a built-in display for local monitoring and adjustment, a robust steel/stainless-steel grey housing with protection category NEMA 4X suitable for demanding environments, and electrical condensate evaporation to avoid drip-related issues. It operates on 400/460 V at 50/60 Hz and includes the e-Comfort controller as standard for efficient regulation.

Advantages

The SK 3305544 combines a high cooling capacity with energy-efficient operation in a compact wall-mounted form factor. The integrated display simplifies on-site reading and parameter changes without additional instrumentation. Its steel housing with NEMA 4X protection supports use in environments where splash and corrosion resistance are required. The electrical condensate evaporation function reduces maintenance related to condensate drainage. The unit’s compatibility with the Blue e ecosystem allows optional IoT integration for remote monitoring when used with the appropriate adaptor.

Suitable for

• Temperature control in electrical enclosures and control cabinets
• Wall-mounted cooling of industrial cabinets in production areas
• Applications requiring NEMA 4X protection against splashing and corrosion
• Installations operating on 400/460 V 50/60 Hz supplies

When it may not be suitable

This cooling unit is intended for cabinet and enclosure cooling; it is not designed as a room air conditioner for open spaces or for direct personal comfort cooling. It may be inappropriate for enclosures that require significantly higher or lower cooling capacities than the stated 1610 W maximum. Also, installations without compatible mounting space or without the required supply voltage (400/460 V) will not be suitable without modifications.

Key specifications

• Input power: 1150 W
• Cooling capacity (maximum): 1610 W
• Supply voltage: 400/460 V, 50/60 Hz
• Housing: steel / stainless-steel grey, wall-mounted
• Protection class: NEMA 4X
• Controller: integrated e-Comfort controller with built-in display
• Condensate management: electrical condensate evaporation

How to use

Mount the unit on the cabinet wall following the manufacturer’s mounting instructions and ensure the enclosure has appropriate access for airflow. Connect the unit to a 400/460 V, 50/60 Hz power supply by a qualified electrician and configure the e-Comfort controller via the built-in display to the desired temperature setpoint. Ensure condensate evaporation function is operational and check seals and filters regularly. If remote monitoring is required, fit the Blue e IoT adaptor compatible with Blue e units to enable connection to the IoT interface.

What to consider before purchase

• Confirm supply voltage compatibility (400/460 V, 50/60 Hz) at the installation site
• Verify required cooling capacity against the unit’s 1610 W maximum
• Ensure available wall-mount space and appropriate enclosure interface
• Assess environmental requirements for NEMA 4X protection and corrosion resistance

Usage recommendations

For reliable operation, perform regular visual inspections, clean or replace filters as recommended, and verify controller settings periodically. Use the integrated display for routine checks; consider IoT adaptor integration for centralized monitoring and trend analysis in larger installations.
