PTC Resettable Fuses

PTC resettable fuses are polymeric positive temperature coefficient (PPTC)fuses used in a variety of electronic circuits and systems. They are designed to protect circuits, systems and components fromovercurrent and overvoltage conditions. These fuses are commonly used inelectronic devices such as power supplies, circuit breakers, and consumerproducts like cell phones.

PTR060V0160-TR Application Field and Working Principle

The PTR060V0160-TR is a PTC resettable fuse. It is ideal for applicationsthat require motor protection, over-voltage, over-current, under-voltage,and short-circuit protection. It also provides instantaneous over-currentprotection. The PTC is designed for both surface-mount and through-holeinstallation. There are four models of this PTR060V0160-TR, including 8A, 10A,15A, and 20A.

The PTR060V0160-TR is designed with two main components: a positivetemperature coefficient (PTC) thermistor, and a fuse element (i.e. aconductor) connected in series. The PTC thermistor acts as the sensingelement, allowing current to flow through the fuse element only when thecurrent reaches a safe level. When the safe level is exceeded, thethermistor begins the resistive state and behaves like a resistor,generating heat and stopping the increased current from flowing. Therefore,the PTR060V0160-TR prevents further current from passing the fuse,protecting the system from any hazards that could be caused byovercurrent.

Once the heating element is cooled to a safe level, the thermistorresumes its original state, allowing the current to pass the fuse again.This safety feature of the PTR060V0160-TR resettable fuse makesit a much safer option compared to traditional fuse by allowing it toreset automatically after the fault is cleared.

Conclusion

The PTR060V0160-TR resettable fuse is a device developed to provideover-voltage, over-current, under-voltage, and short-circuit protection invarious electrical systems. It is designed with two main components: aPTC thermistor and a fuse element. The PTC thermistor acts as thesensing element, allowing current to flow through the fuse element onlywhen the current reaches a safe level. Once the heating element is cooledto a safe level, the thermistor resumes its original state, allowingcurrent to pass the fuse again. This safety feature of the PTR060V0160-TRresettable fuse makes it a much safer option compared to traditionalfuses, allowing it to reset automatically after the fault is cleared.
