2. Resettable fuse - Wikipedia

   en.wikipedia.org/wiki/Resettable_fuse

   A resettable fuse or polymeric positive temperature coefficient device (PPTC) is a passive electronic component used to protect against overcurrent faults in electronic circuits. The device is also known as a multifuse or polyfuse or polyswitch. They are similar in function to PTC thermistors in certain situations but operate on mechanical ...

3. Thermal cutoff - Wikipedia

   en.wikipedia.org/wiki/Thermal_cutoff

   Thermal cutoff. An assortment of thermal fuses. A thermal cutoff is an electrical safety device (either a thermal fuse or thermal switch) that interrupts electric current when heated to a specific temperature. These devices may be for one-time use (a thermal fuse), or may be reset manually or automatically (a thermal switch).

4. Thermistor - Wikipedia

   en.wikipedia.org/wiki/Thermistor

   With PTC thermistors, resistance increases as temperature rises; usually because of increased thermal lattice agitations, particularly those of impurities and imperfections. PTC thermistors are commonly installed in series with a circuit, and used to protect against overcurrent conditions, as resettable fuses.

5. PTC - Wikipedia

   en.wikipedia.org/wiki/PTC

   Positive temperature coefficient, of materials which increase resistance with temperature. Polymeric positive temperature coefficient (PPTC) device or resettable fuse. PTC heating element, a type of self-regulating heater. PTC thermistor, a type of resistor. Positive train control, a type of train protection system.

6. Fuse (electrical) - Wikipedia

   en.wikipedia.org/wiki/Fuse_(electrical)

   Fuse (electrical) A miniature time-delay 250 V fuse that will interrupt a 0.3 A current at after 100 s, or a 15 A current in 0.1 s. 32 mm (1 1/4") long. In electronics and electrical engineering, a fuse is an electrical safety device that operates to provide overcurrent protection of an electrical circuit. Its essential component is a metal ...

7. High capacity oceanographic lithium battery pack - Wikipedia

   en.wikipedia.org/wiki/High_capacity...

   The pack includes diodes in each branch to minimize the possibility of reverse charging the cells. PTCs, or positive temperature coefficient thermistors act as resettable fuses. PTCs begin to get warm at a trip current. The warmth increases their resistance which produces even more heat, and the PTC quickly "trips" and shuts off most of the ...
