9700系列通用型和加強型系列熱保護器，廣泛應用于工業、家用電器電機及電氣設備，防止過流、過熱而產生的非正常工作提供有效可靠的安全保護。加強型外殼適用于塑封電機內置式安裝，可承受3.5Mpa的塑料成型工藝壓力。產品性能符合IEC34-11、GB13232、GB/T13002等標準。
9700 series common & enhanced thermal protectors are widely used in electric motors of industrial, household appliance & other electric equipment. The TH-A1D series can effectively and reliably guard against the damage caused by overflow and overheat. The shell of enhanced type is applicable to the internally installed plastic sealed motors and is capable of tolerating the 3.5Mpa technical pressure for plastic molding. The performance complies with the standards of IEC34-11, GB13232 and GB/T13002 etc.
結構及保護原理(Configuration & principles)
9700系列熱保護器是由導熱金屬外殼、焊有銀合金觸點的雙金屬元件、導電支架、絕緣固定座、靜觸片及耐熱導線等元件組成。電流通過有阻抗的雙金屬元件，遇非正常工作時，隨電流增大或周圍溫度升高至設定溫度值時，雙金屬元件迅速動作，打開觸點，切斷電路。當裝置冷卻到安全工作溫度時，觸點自動閉合，恢復正常工作狀態。
9700 series thermal protector is composed by heat conductive metal shell, bimetal component welded silver alloy contact, current conductive frame, insulated fixing seat, static contact pad and heat resistant wires etc. When the current goes through the bimetal component with impedance, if the current increases or the environment temperature rises and the temperature reaches the preset value, the bimetal component will work and release the contact to shut off the circuit; and by contrast, if the device cools down to the safe temperature, the contact point will reset automatically.

注意(Attentions)
1、由于外殼是金屬導電體，在使用時應配置有導熱且耐溫的絕緣套管。
2、選擇保護溫度時參照A-C曲線圖。
1. The product is covered with a heat conductive and temperature resistant insulated tube because of its shell is made of conductive metal.
2. Please take A-C curve for your reference for your good choice of TH-A1D series thermal protector.
