The CNC KTO011 is a small DIN-rail thermostat for electrical panels and enclosures. Set the dial between 0 and 60°C. While the panel is colder than the setting, the contact stays closed and your heater runs; when the panel warms up to the setting, the contact opens and the heater stops. This keeps panels dry and protects electronics from cold and condensation.
