The KSD301 temperature relay is a type of temperature control switch that uses a bimetallic strip as its temperature-sensing component. Under normal operation, the bimetal remains in a free state, and the contacts are either closed or open. When the operating temperature is reached, the heat-induced internal stress causes the bimetal to act rapidly, either opening or closing the contact to cut off or restore the circuit, thereby regulating the temperature. Once the device cools down to the reset temperature, the bimetal returns to its original shape, and the contacts automatically close or open, restoring normal operation. This is how the KSD301 temperature relay functions.
Now let’s explore the technical specifications of the KSD301 temperature relay. The bimetallic contact temperature-sensitive snap-type thermostat can be either automatically or manually reset, depending on user requirements. It supports both movable and combined working modes. The connection terminals come in various configurations, such as 6.3mm width, 4.8mm flat feet, 45°C bending feet, and 90°C bending feet, offering flexibility for different applications.
The KSD301 series thermostats are widely used in various household appliances and industrial equipment. Some common applications include disinfection cabinets, heaters, microwave ovens, electric kettles, bread machines, electric coffee makers, office equipment, drinking fountains, car seat heaters, car engines, electric steamers, refrigerators, air conditioners, and other small household appliances.
The working principle of the KSD301 thermostat involves a heat-sensitive reaction once the set temperature is reached. As the main part of the appliance heats up, the heat is transferred to the bimetal disc, causing it to act quickly. At the preset operating temperature, the contact opens or closes, cutting off or reconnecting the circuit. When the temperature drops to the reset point, the bimetal returns to its original shape, allowing the contact to re-close or open again, thus controlling the power supply to the circuit.
One of the key features of the KSD301 is its fixed working temperature, reliable action, no arc pulling, long service life, stable performance, immunity to wireless interference, precise structure, and comprehensive functionality.
When installing and using the KSD301 temperature relay, several precautions should be taken. First, ensure that the metal cover of the temperature switch is fully in contact with the controller's mounting surface when using contact temperature sensing. Apply thermal paste on the temperature-sensing surface of the appliance to enhance heat transfer efficiency. Avoid crushing, loosening, or deforming the top of the metal surface during installation, as this could affect the function and accuracy. Do not allow liquid to enter the switch or apply excessive force that might crack the casing. Also, do not alter the shape of the external terminal block, as this could compromise electrical reliability. Ensure proper insulation protection to prevent leakage and ensure safe operation.
The KSD301 offers three main control methods: automatic reset, where the contacts open or close automatically with temperature changes; manual reset, where the contact opens automatically when the temperature rises but must be manually closed after cooling; and one-time action, which is suitable for specific applications requiring single-use functionality.
In terms of technical parameters, the KSD301 operates under the following conditions: a relative humidity of 95% at +20°C, atmospheric pressure between 86–106 kPa, and any working position. It can withstand high temperatures, with ceramic cases rated up to 300°C, PPS plastic cases up to 220°C, and wooden cases up to 160°C.
Key technical specifications include:
- Contact configuration: normally closed or normally open (for automatic reset only).
- Contact load: 250VAC 16A, 10A, 5A or 24VDC 16A, 10A, 5A.
- Insulation resistance: ≥100 MΩ at normal temperature and humidity.
- Contact resistance: ≤100 mΩ.
- Dielectric withstanding voltage: ≥1500VAC.
- Vibration resistance: 50Hz, 0.35mm amplitude.
- Impact resistance: 150m/s².
- Weight: 10g.
- Service life: 100,000 cycles.
These features make the KSD301 an ideal choice for temperature control in a wide range of applications, ensuring safety, efficiency, and long-term reliability.
