Scope
This document applies to arc fault detection devices (AFDDs) for AC circuits in household and similar applications with a rated voltage not exceeding 440 V AC, a rated frequency of 50 Hz, 60 Hz, or 50/60 Hz, and a rated current not exceeding 63 A.
Note 1: The arc fault circuit interrupter (AFCI) in the United States is similar to an AFDD.
AFDDs can be designed by manufacturers as:
— A single device with a disconnecting mechanism that can disconnect the protected circuit under specified conditions; or
— A single device with arc fault protection functionality embedded by the manufacturer into a protective device or assembled with a protective device; or
— A standalone unit that is assembled on-site with a declared protective device in accordance with Appendix D.
The combined protective devices must comply with the requirements for circuit breakers in GB/T 10963.1 or residual current devices (RCDs) in GB/T 16916.1, GB/T 16917.1, and GB/T 22794.
Under certain conditions, if an arc persists, it may cause a fire hazard due to the influence of arc fault current. These devices are intended to reduce the fire risk of fixed electrical installations at the end of the circuit.
Overvoltages caused by disconnected neutral wires in three-phase electrical installations, which may also lead to fires, can also be protected by such devices as an additional option, see 9.22.
Note 2: Trace current can cause arcing, which may lead to a fire.
This document applies to devices that can detect and identify arc current related to fire risks and define the action requirements under specified conditions to disconnect the circuit when the arc current exceeds the limits specified in this document.
AFDDs that comply with this document are suitable for IT systems, except for AFDDs with non-disconnectable neutral wires.
This document does not include AFDDs powered by circuits outside the protected circuit or powered by ba
