Structure and application

KSD301 series product is a kind of thermostat which adopt the bimetal disc as the temperature sensing element. The bimetal disc is in free state and the contacts are closed/open when the electrical appliance is working in normal condition. When the ambient temperature raises to the preset operating temperature, the contacts open/close as the bimetal disc deforms to jump when being heated, then the circuit is cut off/on to control the temperature. Then the contacts will close automatically to cut on the circuit when the electrical appliance is cooled down to the reset temperature, This product is widely used in water dispenser, electrical water boiler, disinfecting cabinet, electrical heating vacuum flask, electrical coffee kettles, rice cooker, air conditioner and etc.


Features: Stabilized performance, high precision temperature controling small bulk, light, high reliability, and little interference to wireless, etc.

Attention

● Pending

○ Approvals

●Please keep the cap firm with the installation surface of the controlled appliance when install. Please wipe conduction silicon grease to the sensing surface in order to ensure effect of the temperature sensing.

●Never collapse, loosen or deform the top of cover surface during installation in order to avoid any influence to its performance.

●Never infiltrateany liquid into the thermostat, nor over press to crack the shell, no changing of the shape of exterior wiring terminal at free will.

●For products used in circuit at no more than 5A current, please choose the lead with cross-section surface of copper core falls within 0.5-1mm2 for connection. And for those used in circuit at no more than 10A current, please choose the lead with corss - section surface of copper core falls within 0.75-1.5mm2 for connection.

●Keep the product in clean dry warehouse at good ventilation and free of corrosive gas and with relative humidity less than 90% and ambient temperature under 40℃.
