2. Circuit breaker - Wikipedia

   en.wikipedia.org/wiki/Circuit_breaker

   A shunt-trip unit appears similar to a normal breaker and the moving actuators are ganged to a normal breaker mechanism to operate together in a similar way, but the shunt trip is a solenoid intended to be operated by an external constant-voltage signal, rather than a current, commonly the local mains voltage or DC. These are often used to cut ...

3. Residual-current device - Wikipedia

   en.wikipedia.org/wiki/Residual-current_device

   A residual-current device (RCD), residual-current circuit breaker (RCCB) or ground fault circuit interrupter (GFCI) [a] is an electrical safety device that interrupts an electrical circuit when the current passing through a conductor is not equal and opposite in both directions, therefore indicating leakage current to ground or current flowing to another powered conductor.

4. Fault current limiter - Wikipedia

   en.wikipedia.org/wiki/Fault_current_limiter

   Further, this change is extremely rapid, before a circuit breaker can trip a few milliseconds later. (High-power circuit breakers are synchronized to the alternating current zero crossing to minimize arcing.) [citation needed] While the power is unstable during the fault, it is not completely disconnected.

5. Resettable fuse - Wikipedia

   en.wikipedia.org/wiki/Resettable_fuse

   The hold current is the maximum current at which the device is guaranteed not to trip. The trip current is the current at which the device is guaranteed to trip. [7] When power is removed, the heating due to the leakage current will stop and the PPTC device will cool.

6. Electrical fault - Wikipedia

   en.wikipedia.org/wiki/Electrical_fault

   Transmission and distribution systems use an automatic re-close function which is commonly used on overhead lines to attempt to restore power in the event of a transient fault. This functionality is not as common on underground systems as faults there are typically of a persistent nature. Transient faults may still cause damage both at the site ...

9. Power strip - Wikipedia

   en.wikipedia.org/wiki/Power_strip

   These power strips have a reset button for the circuit breaker, which is used to return the strip to service after an overload has caused it to trip. On some power strips, the red, lighted rocker switch actually controls a thermal circuit breaker which flips to off when tripped. Resetting is done by flipping the switch back on. [11] [12]
