Applications

Ideal for:

• Industrial control panels and MCCs
• Automation cabinets (PLCs, drives, robotics)
• Telecom and IT racks requiring mixed heating/cooling
• Outdoor enclosures with filter-fan climate control

By activating fans when temperatures rise and heaters when they fall, the thermostat prolongs component life and prevents condensation.

What Customers Say

“Simple to wire and extremely reliable. One part number covers every voltage we use, so spares stocking is painless.” – Panel-build supervisor

Key Features of the Rittal SK 3110.000

• Wide multi-voltage input (24 – 230 V AC / 24 – 60 V DC)
• Compact 71 mm square footprint saves rail space
• High 10 A heating contact rating
• 1 K switching hysteresis for tight control
• Tool-less DIN-rail or snap-in mounting

Comparison with Other Enclosure Thermostats

Unlike fixed-voltage models, the SK 3110.000 eliminates the need to specify different thermostats for each supply, reducing inventory costs. Its change-over contact enables both heating and cooling control from a single device, whereas many low-cost units support only one function.
