PTC Thermistor Current Protect Resettable Fuse Description:

PTC Thermistor Current Protector Resettable Fuse are ceramic-based doped barium titanate PTC thermistors discs, in through-hole rugged design, used instead of conventional fuses to protect load, such as transformers, instruments,  power supply, or electronic circuit, against overcurrent overload and short circuit,  for circuit protection inrush current limit function, by utilizing ceramic PTC thermistors thermal property that resistance increases sharply at Curie Temperature (also called Switch Temperature, Reference Temperature), reduces the current flow to the load to an admissible low level.

PTC thermistors protector not only respond to inadmissibly high currents but also if a preset temperature limit is exceeded.

PTC thermistor over-current protector limits the power dissipation of the whole circuit by increasing their resistance and thus reducing the current to a harmless residual value.

In contrast to conventional fuses, PTC thermistor resettable fuses do not have to be replaced after elimination of the fault but resume their protective function immediately after a short cooling-down time.
