The primary function of this specification is to cover the general requirements for 28 VDC manual reset trip-free arc fault/thermal circuit breakers for use in aircraft electrical systems conforming to MIL-STD-704. As a secondary function, this specification may possibly cover the general requirements for AFCBs for use in primary vehicles, other than aircraft, when mounted directly to the structure.

This specification covers the requirements for current limiter type fuses for use in aircraft primary electrical power systems conforming to MIL-STD-704. These limiters are suitable for use in AS53731 fuse holders for operation at −54 to 125 °C.
The primary function of this specification is to cover the general requirements of one-, two-, and three-phase (often referred to as poles) trip-free circuit breakers for use in aircraft electric systems conforming to MIL-STD-704. As a secondary function, this specification may possibly cover the general requirements of one-, two- and three-phase circuit breakers for use in primary vehicles, other than aircraft, when mounted directly to the structure.
