KSD301突跳式溫控器（溫控開關(guān)、溫度開關(guān)）小型帶外殼的雙金屬片溫控器,是將雙金屬片放置在溫控、溫度開關(guān)的殼體內(nèi)部加以保護(hù)，此種溫控、溫度開關(guān)屬于溫度繼電器類器件.利用碟形雙金屬片在溫度作用下產(chǎn)生瞬間跳動(dòng)的原理,通過機(jī)構(gòu)的作用,使溫控開關(guān)內(nèi)部觸點(diǎn)迅速動(dòng)作,達(dá)到斷開或接通電路的目的.其工作溫度固定,無須調(diào)整;動(dòng)作可靠干脆,電弧小;使用壽命長;無線電干擾少.額定電氣參數(shù):5A系列AC250V 5A/AC125V 7A(阻性負(fù)載) 10A系列AC250V 10A(阻性負(fù)載)弱電系列AC24V 0.5A/DC12V 0.25A常態(tài)電氣強(qiáng)度:AC 50Hz 2000V歷時(shí)一分鐘不擊穿,無閃絡(luò).常態(tài)絕緣電阻:大于100MΩ接點(diǎn)形式:單刀單擲(S.P.S.T)溫控開關(guān)或者溫度開關(guān),可以分為五種類型:室溫下接通,溫度上升觸點(diǎn)斷開,溫度下降觸點(diǎn)接通室溫下接通,溫度下降觸點(diǎn)斷開,溫度上升觸點(diǎn)接通.室溫下斷開,溫度上升觸點(diǎn)接通,溫度下降觸點(diǎn)斷開室溫下斷開,溫度下降觸點(diǎn)接通,溫度上升觸點(diǎn)斷開室溫下接通,溫度上升觸點(diǎn)斷開,手動(dòng)復(fù)位接通.

   KSD301 snap action thermostat is a small-size bimetal thermostat series with a metal cap, which belongs to thrmalrelays’ family. The main principle is that one function of bimetal discs is snapping can push the action lf the contacts through the inside structure, then caused on of off the circuit finally. The main characteristics are the fixation of working temperature, the reliable snap action, less flashover, longer working life and less radio interference.Electric Ratings: AC250V 5A/AC 125V 7A (Resistive load) AC250V/10A (Resistive load)Electric Strength: No breakdown and flashover under AC 50HZ for one minuteInsulation Resistance:＞1000MΩ(with a DC500V mugger)Contacts Form: S.P.S.T. D ibis ion to five tubes:Closes in room temperature.  Opens at temperature rise, closes at temperature decreasing.Closes in room temperature.  Opens at temperature rise decreasing, closes at temperature rise.Opens in room temperature.  Closes at temperature decreasing, Opens at temperature decreasing.Opens in room temperature.  Closes at temperature decreasing, Opens at temperature rise.Closes in room temperature.  Opens when the temperature rise, Closes at temperature decreasing. The action lf close will be finished through manual reset. Earthlings Methods: by the connection of the metal cap of thermostat and the earth-connect metal part of appliance
