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
■ Reduced repair and replacement costs
■ Reduced nuisance tripping
■ Combined overcurrent and overtemperature protector in one device
■ Faster than bimetallic switch designs that take on average
approximately 30 seconds to cool down and reset
■ Generally lower electromagnetic interference than bimetallic switches
