   en.wikipedia.org/wiki/Arc-fault_circuit_interrupter

   The current (as of 2013) devices are referred to as "combination type." An arc-fault circuit interrupter ( AFCI) or arc-fault detection device ( AFDD) [1] is a circuit breaker that breaks the circuit when it detects the electric arcs that are a signature of loose connections in home wiring. Loose connections, which can develop over time, can ...

   en.wikipedia.org/wiki/Fault_current_limiter

   Fault current limiter. A fault current limiter (FCL), also known as fault current controller (FCC), [1] is a device which limits the prospective fault current when a fault occurs (e.g. in a power transmission network) without complete disconnection. The term includes superconducting, solid-state and inductive devices.
