Rittal SK3110.000 Enclosure Thermostat — DIN Rail Mounted, 5–60 °C

One thermostat. Every voltage. The Rittal SK3110.000 covers the full range from 24–230 V AC and 24–60 V DC without modification, eliminating the need to specify separate models for different supplies — simplifying both procurement and stock management. Its single-pole changeover contact gives you independent control of both heating and cooling devices from a single unit, while the compact DIN rail design fits neatly into any control panel.

• Temperature range: 5 °C to 60 °C (adjustable)
• Voltage: 24–230 V AC / 24–60 V DC (universal)
• Contact: SPDT changeover — controls heating and cooling independently
• Mounting: 35 mm DIN rail (EN 50022), vertical or horizontal

Ideal for panel builders and automation engineers who need a reliable, low-maintenance thermal control solution for electrical enclosures.

Key Advantages

• Universal voltage range (24–230 V AC / 24–60 V DC) — one SKU covers all supply configurations, reducing inventory.
• Changeover contact enables independent control of both heating and cooling from a single device.
• Bi-metal sensing element with thermal feedback for accurate, drift-resistant temperature detection.
• Vertical or horizontal DIN rail mounting with snap-in adapter included for TS/SE enclosure sections.
• External screw terminal connections — time-saving wiring without opening the thermostat body.
• UL + C-UL listed and VDE approved for use in regulated and certified installations.
• Prevents overheating and condensation, extending component service life.

Why Choose SK3110 Over Dual Thermostats?

Unlike systems that require separate thermostats for heating and cooling, the SK3110.000 uses a single SPDT changeover contact to control both functions independently. This reduces panel complexity, minimises wiring time, lowers component count and improves long-term reliability by reducing potential failure points.

Efficient Thermal Management for Control Cabinets

The SK3110.000's changeover contact allows it to activate cooling (e.g. filter fans) and heating (e.g. enclosure heaters) from a single device.

Typical Applications

• Electrical enclosures and control panels
• Fan and heater switching
• PLC temperature signalling
• Industrial automation cabinets
