China SPST Bimetal Limit Snap Thermal Switch Supplier

SPST-NO/NC Bimetal thermal switch Applications include electric motors, 加熱器, 變形金剛, thermal coils, electronics, HVAC, and white goods. China Custom Limit Snap bimetal thermal switch (250v 10a / 125v 16a) is a temperature sensing device which is made with a formed 1/2′′ or 3/4′′ bi-metal disc that “snaps” at a preset temperature. YAXUN KSD9700, ST-22系列, TB02 Series Bimetal Snap-Action Temperature Switches are based on a bimetal snap disc two-contact system with response sensitivity to a combination of temperature and current. The functions of these switches include thermal motor protection, temperature limiting, and thermal cut-off. The series features high power ratings and no vibrational noise, with availability in normally closed or normally open configurations. The KSD302/17AM/6ap/S06/S01 Series switches are sealed so they can be used in vacuum-impregnated applications with various varnishes and glues. The rated maximum currents are 6.3A (type T12) with maximum switching currents of 60A. A low tolerance of ±1K is possible with the T10 models. KSD302 Series Bimetal Snap-Action Temperature Switches are available in a wide range of packaging, mounting, and design options and can be wired in twin or triplet configurations.

●KSD301, KSD302, KSD303 series Limit Snap Thermal Switch Notice
⑴ grounding: The thermostat metal cover metal parts connected to the equipment grounding.
⑵ when using contact temperature installation should be charged with snapping the metal to cover up the installation of surface equipment, to ensure that the temperature effect, should be coated with thermal grease or other properties like heat transfer medium in surface temperature.
⑶ not install when the top cover surface collapsed, loose or deformed, so as not to affect performance.
⑷ not allow liquid to penetrate the internal temperature, not cause the shell cracks, not free to change the shape of the external terminals.
⑸ product in less than 5A current of the circuit used, should be selected cross-section of 0.5 5-1㎜2 copper wires; not more than 10A current in the circuit, chose the copper wires cross-section 0.75-1.5㎜2 .
⑹ product should be less than 90% 相對濕度, 環境溫度低於 40 °C通風, 乾淨, 乾, 儲存喺倉庫中嘅非腐蝕性氣體.
⑺ use can not bend the terminals, otherwise it will affect the reliability of the electrical connections.
