Thermal Protector 17am, 7am

We are supplying 17AM Thermal Overload Protectors in Yancheng, Jiangsu, China.

Introduction
17AM series products are thermal protector using double metal as the temperature sensing element, which has the double protection function of temperature and the over current. 17AM can be applied for transformers; battery; lighting electrics; cleaning machine; water pump; electric tools; electric heating pad; and the household appliances.

Work Principle
The principle is easy and effective, the metal pieces action is as per the current on the protector and the ambient temperature. if the temperature reaches the trip temperature, the double metal piece acts fast to cut off the power. When the temperature lows to the restore temperature, the contact is back to position. The double metal piece can supply the thermal sensibility and the current sensibility at the overload condition. When blocking, the combination of the metal piece and the resistance heating fuse can supply the very precise tripping time, and supply the maximum protecting.

Features
1.The dual protection by temperature and current;
2.The special combination of double metal piece and the resistance heating fuse can keep the very precise tripping time to prevent the motor over high temperature;
3.The sleeve wire resistance of the double metal piece can be used to each application premium current and time characteristics;
