How to tell if a sefuse NEC temperature fuse (Lämpösulake) is good or bad?
The following steps can be used to measure the quality of a temperature fuse (Lämpösulake) :
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. Yleensä, 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.

250v 2a /10a Lämpöleikkauslenkki pöytätuulettimeen/sekoittimeen
Lämpösulake voi havaita sähkö- ja elektroniikkatuotteiden epänormaalin toiminnan aiheuttaman ylikuumenemisen, katkaisemalla siten piirin tulipalon välttämiseksi. Yleisesti käytössä: hiustenkuivaajat, sähkösilitysraudat, riisinkeittimet, sähköliesi, muuntajat, moottorit, vesiautomaatit, kahvipannuja, jne. Lämpösulaketta ei voi käyttää uudelleen käytön jälkeen, ja toimii vain kerran sulamislämpötilassa.
thermal fuse and circuit breaker cutoff temperature
They are the same in that they can achieve short circuit protection. The principle of a thermal fuse is to use a current flowing through a conductor to cause the conductor to heat up. When the melting point of the conductor is reached, the conductor is melted so that the circuit-protected electrical appliances and lines are not burned.
Thermal Fuse Function and Application
The Thermal Fuse (Thermal Cutoff, Lämpötilasulake) is Axial / Radial / Organic Thermal-Link(OTCO) safety parts that stops the flow of electricity to the motor circuit when a overheats. If the fuse is missing or broken, your motor will not start. The thermal fuse is sensitive to external temperature, and the operating temperature is accurate and stable. Pieni koko, tiivistetty rakenne. Luotettava suorituskyky. Low resistance value. Kertatoimi katkaisee virran, and the current interruption capacity reaches 250VAC/25A.
