KSD301 Bimetaalskyflimiettermostate : Funksie, Spesifikasie, Temp Switch

KSD301, 302 series snap-action are thermostats that use bimetallic discs (1/2″ skyf) as temperature sensing components to control thermal cut-off switches. Elektriese gradering: AC 125V max 15A~60A; AC250V 5A 10A 15A max 16A. Action Temperature: -30 °C~280 °C. When household & industrial appliances are working normally, die bimetaalstrook is in 'n vrye toestand en die kontakte is in 'n geslote/oop toestand. When the temperature reaches the action temperature, the bimetallic strip is heated to generate internal stress and quickly moves, die kontakte oopmaak/toemaak, die stroombaan af te sny/koppel, 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. Moenie ineenstort nie, loosen or deform the top of the cover during installation to avoid affecting performance.
3. Moenie toelaat dat vloeistof in die termostaat binnedring nie, do not allow cracks to appear on the outer shell, en moenie die vorm van die eksterne terminaal na goeddunke verander nie.
4. When the product is used in a circuit with a current of no more than 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. Die produk moet in 'n pakhuis gestoor word met 'n relatiewe humiditeit van minder as 90% and an ambient temperature below 40℃, which is ventilated, skoon, dry, and free of corrosive gases.

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