Ksd301 S.P.S.T Температурен превключвател

The Ksd301 temperature switch is a temperature switch using a bimetal as a temperature sensing element. Когато уредът работи нормално, the bimetal is in a free state and the contacts are in a closed / open state. When the temperature rises to the operating temperature value, the bimetallic element acts quickly due to the internal stress generated by the heat, opening / closing the contacts, and cutting / connecting the circuit, thereby providing thermal protection. When the temperature drops to the reset temperature, the contact will be closed / opened automatically and the normal working state will be restored. Widely used in household appliances motors and electrical appliances, such as washing machine motors, air-conditioning fan motors, трансформатори, баласти, електрически отоплителни уреди, и т.н.

● KSD301 series thermostat Caution
⑴ grounding: The thermostat metal cover is connected to the equipment grounding metal parts.
⑵ when using a contact temperature installation should be closely aligns the charged surface of the metal lid of the appliance mounting surface to ensure that the temperature effect. should be coated with thermal grease or other similar performance thermal media in surface temperature.
⑶ installation can not cover the top surface collapsed, loose or deformed, so as not to affect the performance.
⑷ not allow the liquid to penetrate the internal temperature, not cause the shell cracks, not free to change the shape of the external terminals.
⑸ product is not greater than 5A current in the circuit, should be selected cross-section of 0.5 5-1㎜2 copper core wire connection; not more than 10A current in the circuit, should be selected cross-section of copper conductor wire connection 0.75-1.5㎜2 .
⑹ products should be less than 90% relative humidity, ambient temperature below 40 ℃ ventilated, чиста, суха, non-corrosive gases stored in the warehouse.
⑺ use can not bend terminals, otherwise it will affect the reliability of the electrical connection.
