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

Custom Built in Thermal Fuse link and cable
The thermal fuse is a thermal protector. Thermal fuses are mainly composed of melts and tubes, plus external fillers. When using, connect the thermal fuse in series with the protected circuit. When the current of the protected circuit exceeds the specified value, and after a certain period of time, the melt generated by the melt itself fuses the melt, breaking the circuit, thereby protecting the circuit. Electrical appliances that use a metal conductor as a melt to break a circuit are connected in series in the circuit.
Emerson G4 / G5 series microtemp 10A / 20A thermal fuse
Emerson Group production MICROTEMP® G4 G5 series thermal fuse, According to different product specifications, Rated load current, respectively, up to AC250V 10A, AC120V 15A and DC24V 5A. To provide reliable protection against overheating, In the same industry products, MICROTEMP® G4 G5 series thermal fuse has established its flagship status can not be shaken.
SET Square TCO Thermal Fuse use Flat iron
A piece of fusible alloy wire is connected between the two pins of the thermal fuse, which is covered by a special transparent resin square shell. Current can flow from one pin to another. When the temperature around the thermal fuse rises to its set operating temperature, its fusible alloy wire melts and shrinks into a spherical shape, and is attached to the ends of the two pins with the help of surface tension and special resin. In this way, the circuit is permanently cut off.
