Advantages
Benefits
Resettable feature with overtemperature and overcurrent 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
Reduced repair and replacement costs
Reduced nuisance tripping
Combined overcurrent and overtemperature protector in one device
Generally lower electromagnetic interference than bimetallic switches
