Equipment that switches, isolates and protects electrical circuits, including circuit breakers, switchgear, ring main units, vacuum interrupters, reclosers, surge arresters, fault current limiters, arc-fault and residual-current devices and transfer switches. A technology belongs here when its cited article describes such a switching or protective device. These devices open, close, isolate and protect circuits when something goes wrong, from residential protection devices to the switchgear of substations. A device is placed here by the switching or protective role the cited article describes.

A lightning arrester (alternative spelling lightning arrestor) (also called lightning isolator) is a device used on electric power transmission and telecommunication systems to protect the insulation and conductors of the system from the damaging effects of lightning.
Fault current limiter - Wikipedia
Has Member: Fault Current Limiter, LeadQuote, Has Member: Fault Current Limiter, Lead
A fault current limiter (FCL), also known as fault current controller (FCC), is a device which limits the prospective fault current when a fault occurs (e.g. in a power transmission network) without complete disconnection.

Has Member: Arc-Fault Circuit Interrupter, LeadQuote, Has Member: Arc-Fault Circuit Interrupter, Lead
An arc-fault circuit interrupter (AFCI) or arc-fault detection device (AFDD) is a circuit breaker that breaks the circuit when it detects the electric arcs that are a signature of loose connections in home wiring.
