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 ...

An arc fault is a high power discharge of electricity between two or more conductors. This discharge generates heat, which can break down the wire's insulation and trigger an electrical fire. Arc faults can range in current from a few amps up to thousands of amps, and are highly variable in strength and duration.
The ZSIP system allows faster instantaneous trip settings to be used, without loss of selectivity. The faster trip times reduce the total energy in an arc fault discharge. Arcing time can significantly be reduced by protection based on detection of arc-flash light. Optical detection is often combined with overcurrent information. [13]
Arc-fault circuit interrupter (AFCI) or arc-fault detection device (AFDD) — detects electric arcs from the likes of loose wires. Recloser — A type of circuit breaker that closes automatically after a delay. These are used on overhead electric power distribution systems, to prevent short duration faults from causing sustained outages.
The device numbers are enumerated in ANSI/IEEE Standard C37.2 Standard for Electrical Power System Device Function Numbers, Acronyms, and Contact Designations. Many of these devices protect electrical systems and individual system components from damage when an unwanted event occurs such as an electrical fault.
