ST01 series thermal protector has the following features: miniature size, no current heat effect, accurate temperature response, temperature sensitive, compact and pressure stable, etc. It is widely used in fractional electric motors, transformers, coils, electronics and sensors for thermal overheat protection.
Rated current (COSΦ=1.0)
Rated open temperature: 60ºC~165ºC(details as per attached list)
Reset temperature: 35ºC~110ºC(details as per attached list)
Electric strength(the test instrument is high voltage tester)
When the product is in the breaking state, the lead wires should be able to withstand AC500V lasting for 1min without breakdown or flashover;
The part between the lead wires and the case should be able to withstand AC1500V lasting for 1min without breakdown or flashover;
Insulation resistance: Under normal conditions, the insulation resistance between leads (terminal) and case should be more than 100MΩ measured by ohmmeter of DC500V.
Contact resistance: The contact resistance of standard lead length products should be lower than 50mΩ.
Tensile resistance test: Terminal & leads should endure more than 30N axes direction pull lasting for 1 minute without break orloosness.
High temperature test: Keep the thermal protector in an incubator environment of 30 degree higher than its rated switching temperature for ninety six hours, and test it two hours later after taking out from the incubator, while the temperature change does not exceed the initial value of ± 5 ºC or ± 5%, returns the maximum value.
Low temperature resistance test: Keep the thermal protector in a -40ºC incubator for ninety six hours, and test it two hours later after taking out from the incubator, while the temperature change does not exceed the initial value of ± 5 ºC or ± 5%, returns the maximum value.
Anti-Vibration test: thermal protector should be able to withstand the amplitude 1.5mm, frequency 10 ~ 55Hz, scanning change cycles of 3 ~ 5 times /min. The vibration direction X, Y, Z and each direction vibrates on a continuous basis for 2 hours while the temperature change does not exceed the initial value of ± 5 ºC or ± 5%, returns the maximum value.
When the thermal protector is in series connection with RL1-15A fuse to withstand short circuit current limit of 200A, it should not cause the cotton burned which is wrapped on the thermal protector.
In the conditions of rated voltage, current and power factor 0.7, the product can be normal on-off 10000 times operated due to external heat source.
For action temperature testing, temperature rising rate should be controlled at 1ºC/1min and use indicator light to show the on/off state. The testing current should be no more than 0.01A
In use, the thermal protectors could not withstand a big impact and stress.
Matters this standard does not involve or customers having other requirements shall be separately set.
