Best Selling Thermal Cutoff Fuse Thermo Switch RoHS Compliant UL VED PSE Certification

Best Selling Thermal Cutoff Fuse Thermo Switch RoHS Compliant UL VED PSE Certification

Product detail

To maximize product life, we suggest a 30℃ minimum differential between operating ambient temperature at the thermal cutoff location and your selected “Rated Functioning Temperature”.

Under no conditions should the thermal cutoff be exposed to a continuous normal ambient temperature in excess of 200℃.

Nota: only proper testing of the above will help you in determining the selected thermal cutoff’s suitability within the application.

Temperature increasing according to UL standard: 1℃ / mínimo

TF (Rated Functioning Temperature)
The temperature of the thermal cutoff which causes it to change its state of conductivity with a detecion current up to 10 mA as the only load. Under the UL/IEC standards the tolerance is +0℃, -10℃.

TH (Holding Temperature)
The maximum temperature of the thermal cutoff at which it will not change its state of conductivity for 168 hours while conducting its rated voltage. It is called Th for short by UL and called Tc by IEC/VDE.

TM (Maximum Temperature Limit)
The tmperature of the thermal cutoff, up to which the mechanical and electrical properties of the thermal cutoff, having changed its state of conductivity, will not be impaired for 10 minutos.
