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 .
AFCI receptacles offer the benefit of localized test and reset with such buttons located on the face of the device. This can save a journey to the breaker panel but can also encourage simply resetting by a user without investigating the underlying fault, as would presumably happen if someone with access to the electrical panel was notified.
Automatically closing the breaker after it has tripped and stayed open for a brief amount of time, usually after 1 to 5 seconds, is a standard procedure. [ 5 ] Reclosers are often used as a key component in a smart grid , as they are effectively computer controlled switchgear which can be remotely operated and interrogated using supervisory ...

A residual-current device (RCD), residual-current circuit breaker (RCCB) or ground fault circuit interrupter (GFCI) [a] is an electrical safety device, more specifically a form of Earth-leakage protection 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 ...
