KSD301 Bimetal Disc Limit Thermostats : Функција, Спецификација, Temp Switch

КСД301, 302 series snap-action are thermostats that use bimetallic discs (1/2″ диск) as temperature sensing components to control thermal cut-off switches. Electrical Rating: AC 125V max 15A~60A; AC250V 5A 10A 15A max 16A. Action Temperature: -30 °C~280 °C. When household & industrial appliances are working normally, биметална трака је у слободном стању а контакти су у затвореном/отвореном стању. When the temperature reaches the action temperature, the bimetallic strip is heated to generate internal stress and quickly moves, отварање/затварање контаката, одсецање/повезивање кола, thereby playing a role in temperature control. When the appliance cools to the reset temperature, the contacts automatically close/open and resume normal working state.

Напомене
1. (KSD301 surface mount thermostat) When using contact temperature sensing surface mount for installation, the metal cover should be close to the installation surface of the controlled device to ensure the temperature sensing effect. Thermal conductive silicone grease or other thermal conductive media with similar performance should be applied to the temperature sensing surface.
2. Немојте се срушити, loosen or deform the top of the cover during installation to avoid affecting performance.
3. Не дозволите да течност продре у термостат, do not allow cracks to appear on the outer shell, и не мењајте облик спољашњег терминала по вољи.
4. Када се производ користи у колу са струјом не већом од 5А, a cable with a copper core section of 0.5-1㎜2 should be selected for connection; when used in a circuit with a current of no more than 10A, a cable with a copper core section of 0.75-1.5㎜2 should be selected for connection.
5. Производ треба чувати у складишту са релативном влажношћу ваздуха мањом од 90% and an ambient temperature below 40℃, which is ventilated, чиста, сува, and free of corrosive gases.

Classification of KSD301:
It can be classified by temperature, материјала (bakelite/ceramic), or installation method (surface mount/nut fixing).
Classification by action nature: It can be divided into normally open & normally closed action, аутоматско ресетовање & ручно ресетовање.
