KSD301 Bimetal Disc Limit Thermostats : Fungsi, Spesifikasi, Temp Switch

KSD301, 302 series snap-action are thermostats that use bimetallic discs (1/2″ cakram) as temperature sensing components to control thermal cut-off switches. Peringkat Listrik: AC 125V max 15A~60A; AC250V 5A 10A 15A maks 16A. Suhu Aksi: -30 °C~280 °C. When household & industrial appliances are working normally, the bimetallic strip is in a free state and the contacts are in a closed/open state. When the temperature reaches the action temperature, the bimetallic strip is heated to generate internal stress and quickly moves, membuka/menutup kontak, memutus/menyambungkan rangkaian, 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.

Notes
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. Do not collapse, loosen or deform the top of the cover during installation to avoid affecting performance.
3. Do not allow liquid to penetrate into the thermostat, do not allow cracks to appear on the outer shell, and do not change the shape of the external terminal at will.
4. Bila produk digunakan dalam rangkaian dengan arus tidak lebih dari 5A, 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. The product should be stored in a warehouse with a relative humidity of less than 90% and an ambient temperature below 40℃, which is ventilated, membersihkan, kering, and free of corrosive gases.

Classification of KSD301:
It can be classified by temperature, bahan (bakelite/ceramic), or installation method (surface mount/nut fixing).
Classification by action nature: It can be divided into normally open & normally closed action, pengaturan ulang otomatis & pengaturan ulang manual.
