Resettable feature with over temperature and over current protection can save expensive components from having to be replaced after tripping, e.g., transformers with built in thermal fuses
Faster than bimetallic switch designs that take on average approximately 30 seconds to cool down and reset
Generally lower electromagnetic interference than bimetallic switches
Reduced repair and replacement costs
Reduced nuisance tripping
Combined over current and over temperature protector in one device
