  • Controls water-cooler temperature between 37 °F and 61 °F
  • Capillary length of 48 in allows flexible mounting
  • SPST switch closes on temperature rise for reliable operation
  • Rated 10 A full-load and 40 A locked-rotor current
  • Certified to CSA, ENEC and UL safety standards

Water Cooler Control

The Ranco K-3001 is a thermostatic switch designed to regulate water cooler compressors. It opens and closes a single-pole single-throw contact based on the temperature sensed by its 48-inch capillary tube. The control range spans from 37 to 61 degrees Fahrenheit with a switch action that closes on temperature rise.

Installation Compatibility

Verify that the application requires a control with a 37-degree cold-off setting and a normally-off temperature of 46 degrees Fahrenheit. The unit carries CSA, ENEC and UL listings, so confirm these standards meet local code requirements. Ensure the available mounting space accommodates the overall height of 1 9/16 inches and length of 1 5/8 inches.

Electrical and Thermal Performance

In normal operation the switch handles a full-load current of 10/6/6 amps and a locked-rotor rating of 40/36/36 amps. The compressor will typically start when the temperature reaches 53 degrees Fahrenheit and stop once it falls to 37 degrees Fahrenheit. This cycling keeps the cooler within the intended temperature band without continuous running.
