СЕФУСЕ НЕЦ СФ Цутоффс Термални осигурач ОЕМ/ОДМ сервис

Како знати да ли је сефусе НЕЦ температурни осигурач (Топлотни осигурач) је добро или лоше?
The following steps can be used to measure the quality of a temperature fuse (Топлотни осигурач) :

Use a multimeter to measure the resistance value: Set the multimeter to the resistance value measurement position, and then connect two test pens to the two ends of the Thermal Fuse . If the fuse is not blown, its resistance value should be very small. If the fuse is blown, the resistance value will be a larger number. If you are not sure about the correct resistance value, you can refer to the product manual or consult the manufacturer. ‌

Observe the color change: If the Thermal Fuse turns black or the resistance value is abnormally high, it needs to be replaced.

The following matters need to be noted during the measurement process:
Lead bending: When bending the lead, it should be bent from a part more than 6 mm away from the root, and the root and lead should not be damaged. Do not forcibly pull, press, or twist the lead. ‌
Welding operation: When welding the lead, the heating humidity should be limited to a minimum, and be careful not to apply high temperature to the thermal fuse. Do not forcibly pull, press, or twist the thermal fuse and lead. After welding, it should be cooled for more than 30 seconds immediately.
Use conditions: Thermal fuses can only be used under the conditions of specified rated voltage, current and specified temperature. Pay special attention to the maximum continuous temperature that the thermal fuse can withstand.

Additional suggestions and common problems:
Replacing fuses: When a thermal fuse burns out, it needs to be replaced with a new fuse with the same voltage and rated temperature. Обично, thermal fuses are designed to be push-pull, so you only need to gently pull out the old fuse and insert the new one.
Regular inspection: When using electrical appliances, electronic equipment, and automobiles, it is very important to regularly check whether the thermal fuse is burned out.
