Performance

1. The tolerance of action temperature:±5℃, the reset temperature according to actual setting value;

2. The thermal protector can should be able to withstand AC1500V, 1min or AC1800V,1s between lead wire and insulation sleeving, no breakdown flash-over phenomenon, the leakage current should be below 1mA；

3. Under normal conditions, the insulation resistance between lead wire and insulation sleeving is more than 100MΩ(The meter used is DC500V insulation resistance gauge)；

4. Contact resistance less than 50Mohm (or customized value);

5. Exposed to the air condition of 150℃ for 96 hours, no damage;

6. Exposed to relative humidity 95% RH at a temperature of 40℃ for 48hours, no damage;

7. Dropped freely from 70cm height to the plastic or wooden floor once without damage;

Product Design and Working Principle

1. Both temperature and current sensitive function

1.1 Current overload protection principle

The current flows the case terminal, bimetal strip or auxiliary heating wire(which is connected with stationary contact of the bottom board), then the bottom board terminals is connecting to application(such as motor and transformer etc.) in circuit, when the application causes the over-current or locked-rotor current to exceed the prescribed value, the thermal protector cut the power off within the set time, so that the application are protected.

1.2 Temperature Protection Principle

The current flows the case terminal and bimetal strip, then the bottom board terminals is connecting to application(such as motor and transformer etc.) in circuit, when the application works abnormally, which causes the ambient temperature to exceed the setting value, the thermal protector cut the power off ,when the ambient temperature will decrease and then the protector will close again.

2. Power cutting and time delay protection

2.1 Work-Operating

The protector is connected to PTC in parallel, then connected to application in series.When the application is working normally, the current will flow through protector.PTC will not work.

2.2 Time delay protection

When the application works abnormally, which causes the ambient temperature to exceed the prescribed value, the protector will open. Then, the current flows through PTC. Since PTC has a very high resistance, the current assigned to the application will be too flow to start it.Meanwhile, the heat generated by PTC will remain the protector open until the power is unplugged.
