1.Temperature Control Accuracy: The KSD 301 has the best temperature control, consequently the appliances are much less likely to go over the safe temperature limits before damaging their interior components or before ceasing to work.
2.Temperature Range: The thermostat can be maintained within a relative temperature range, typically from -20°C to 180° Celsius degrees, which will provide applicable versatility.
3. Snap Action: The KSD 301 uses a snap-action which will provide a fast action with reliable switching, which gives it the ability to quickly respond to the temperature range and maintain the appliance or system within the allowable limits.
4. Auto and Manual Resets: Based on the model, the KSD 301 will either have an automatic resetting mechanism which will reset at less than the preset level, or a manual reset allowing an opportunity to inspect the appliance/unit before returning into service.




The KSD 301 is appropriate for many applications in residential and industrial applications:
1 - Home Appliances: The KSD 301 can be found in electric kettles, toasters, hair care equipment, coffee makers, and similar appliances wherein the KSD would prevent overheating and control the safe operating temperature.
2 - Industrial Equipment: The KSD 301 can be used in heating elements, motors, boilers and transformers in which maintaining temperatures within safe operating limits is paramount.
3 - HVAC Systems: The KSD 301 allows space heaters, cooling and air conditioning systems to operate efficiently while controlling the temperature to prolong systems life.
4 - Refrigeration: The KSD 301 thermostat in refrigeration applications will monitor the temperature in order to maintain temperatures, therefore eliminating energy waste while protecting the equipment.
