Question.4
What is the difference between a thermal fuse and a PPTC resettable fuse?
Select Answer
Both protect from overtemperature only, but PPTC resets while thermal fuse is one-time.
PPTC protects from overcurrent while thermal fuse protects from over temperature.
Thermal fuse protects from overcurrent, while PPTC protects from overtemperature.
Both work the same way, PPTC used in DC lower voltage and thermal fuse is used only in AC high power circuits.
