    Automobile electrical circuit breaker with resettable switch. Automotive fuses are a class of fuses used to protect the wiring and electrical equipment for vehicles. They are generally rated for circuits no higher than 32 volts direct current, but some types are rated for 42-volt electrical systems. They are occasionally used in non-automotive ...

    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 .

    en.wikipedia.org/wiki/Circuit_breaker

    A small circuit breaker typically has a manual control lever to switch the circuit off or reset a tripped breaker, while a larger unit may use a solenoid to trip the mechanism, and an electric motor to restore energy to springs (which rapidly separate contacts when the breaker is tripped).

    Some companies manufacture resettable miniature thermal circuit breakers, which screw into a fuse socket. [14] [15] Some installations use these Edison-base circuit breakers. However, any such breaker sold today does have one flaw. It may be installed in a circuit-breaker box with a door.

  6. Thermal cutoff - Wikipedia

    en.wikipedia.org/wiki/Thermal_cutoff

    A thermal switch (sometimes thermal reset or thermal cutout (TCO)) is a device which normally opens at a high temperature (often with a faint "plink" sound) and re-closes when the temperature drops. The thermal switch may be a bimetallic strip, often encased in a tubular glass bulb to protect it from dust or short circuit. Another common design ...

    en.wikipedia.org/wiki/Recloser

    To prevent electric power distribution network damage, each station along the network is protected with circuit breakers or fuse cutouts which turn off power in the event of a short circuit. These protection solutions present a major problem when restoring power immediately following transient events, because repair crews need to manually reset ...
