FAQ

1. Can I get a customized thermal protector from you?

Yes. We are providing customized service for our noble customers. If you need a customized thermal protector sample, please kindly tell us the following parameters:

1) Rated voltage and Current

2) Action temperature

3) Dimensional requirements

4)Overloading or Tripping current if needed

5) Application and relevant special demands

6) Potential order quantity.

If the customized thermal protector has the same dimension as our current models, and you only need special parameters, we would not charge any cost for 5 pcs samples. If the requested dimensions are different, we may need to build new toolings for this customization. It would cause extra cost and we can negotiate separately.

2. What parameters should I provide when I am trying to ask for thermal protector samples?

If you need to have temperature sensitive thermal protector samples, please prepare the following parameters:

1. Rated voltage, current

2. Action temperature of thermal protector

3. Leadwire length, type and temperature rating.

4. Application of thermal protector.

5. Mounting requirements if needed, including dimensional requirements.

If you want to have current sensitive thermal protector samples, you may prepare three more parameters besides the above:

1. Trip off current

2. Trio off time

3. Normally working temperature of thermal protector. It can not trip off under this temperature.

3. When and why do we need gold contacts of thermal switch?

1. If you need the contact resistance of thermal switch is less than 15 mOhm, you need gold contacts. The resistance of gold contacts is much smaller than silver contacts.

2. If the rated current of thermal switch is 250 mA or less, Gold contacts are necessary.  It can prevent oxidation of the contacts at low current rating. Oxidation forms an insulation film on the silver contacts and low current does not arc enough to burn off the oxidation.

4. How can we conduct the incoming test for your thermal switch?

Incoming test for thermal switch includes temperature test under No-Load, mock-up test under load, functional test in applications and appearance inspection. Since mock-up test, functional test and appearance inspection can be easily done in the customers’ factories, we will only explain how to conduct temperature test under No-Load here.

1. Put the thermal switch inside of a test oven. The air flow speed of the oven needs to be over 200m/min

2. The measuring thermal couple should be as close to thermal switch as possible. An indicator of showing ON/OFF should be provided. The current flowing through thermal switch is less than 0.01A

3. Increasing the air temperature inside of the oven slowly. When air temperature increases to the 10C lower than the bottom tolerance limit of rated temperature value, the further temperature increasing speed has to be controlled at 0.5K/min.

4. When the temperature reaches the tolerance of thermal switch, the bimetal will actuate the contact and cut the circuit off. After that, the operator can open the cover of test oven and let the temperature decrease down. Then, the thermal switch will turn ON again.
