5、aft, Trip-Free 28 VDC RATIONALEThis specification has been developed to provide a means of compliance for qualification of 28 VDC arc fault circuit breakers or alternate product solutions. FOREWORDThermal circuit breakers are designed to react to the heating effect of current carried by wire; and to
6、 protect the wire insulation from thermal damage. These protective devices are not designed to detect or react to the short duration of arcing faults that typically occur outside (before approaching) the defined trip region, or Time versus Current curve, of the thermal circuit breakers.In addition,
7、arc impedance can reduce low voltage fault current magnitudes appreciably. AFCBs combine active arc fault detection with thermal overload protection into one package. Supplemented with the arc fault detection, the AFCB provides an equivalent level of thermal protection of existing thermal circuit br
8、eakers (typically qualified under AS58091), with the added ability to detect and react to arc fault conditions, thereby mitigating damage that will occur to the wiring system by protracted arcing events. It is important to note that the primary purpose of the AFCB as stated above is to mitigate dama
9、ge to the aircraft wiring from the circuit breaker to the first serial load element (examples: LRU, transformer, ballast, rectifier, or connected equipment, etc.). In doing so, the potential of igniting surrounding materials is reduced, but not eliminated. Use of AFCBs for hazard mitigation/preventi
10、on beyond its intended function of mitigating damage to the aircraft wiring should be carefully analyzed and evaluated. NOTE: AS58091 was used as the base document for this AFCB specification as such the tables comprehend future amp rating expansion from 1 to 100 A. SAE AS6019 Page 2 of 60 1. SCOPE
11、1.1 Scope 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
12、requirements for AFCBs for use in primary vehicles, other than aircraft, when mounted directly to the structure. 1.2 Classification AFCBs shall be the Thermal Type, and classified into different styles. Variations from the basic style of each AFCB shall be indicated by the part number from the appro
13、priate specification sheet (see 3.1). 1.2.1 Styles AFCB styles shall consist of all part numbers covered by one Aerospace Standard or specification sheet. For example: a. All part numbers of AS6019/1 shall be the same style. b. All part numbers of AS6019/2 shall be the same style. The same style cla
14、ssification applies to all Aerospace Standards and specification sheets covered by this specification. 1.2.2 Part Number The part numbers for AFCBs in accordance with this specification shall conform to part number scheme below. Alphanumeric characters shall be used to designate variations from the
15、basic style of each circuit breaker. Example of part number scheme: When a designator for a variation is not applicable it shall be omitted from the part number. Not all letters are applicable for every specification sheet. Refer to the latest specification sheet and QPL for available and qualified
16、configurations. 1.2.3 Amperage Ratings The amperage rating designator shall be a number specified in each specification sheet to indicate the nominal amperage rating for overload protection. 1.2.4 Pushbuttons The AFCB pushbutton shall be designated as follows. Standard length pushbutton, as specifie
17、d in the specification sheet shall have no designator letter. L - Extra length pushbutton (see 6.3.9) SAE AS6019 Page 3 of 60 1.2.5 Auxiliary Switch Terminals The use of auxiliary switch terminals when allowed by the specification sheet shall be designated as follows. AFCBs with standard terminals o
18、nly, as specified in the specification sheet, shall have no designator letter. A - Auxiliary switch terminals 1.2.6 Vibration Level The vibration level of the AFCB shall be specified in the specification sheet and shall be indicated in the part number by one or more of the following designators. Sta
19、ndard sine vibration capabilities shall have no designator (see 4.7.11.2). V - High Level sine capabilities (see 4.7.11.3). C thru K - Random vibration capabilities (see 4.7.11.1). 1.2.7 Mounting Configurations Unless otherwise specified, the AFCB mounting configuration shall be designated as follow
20、s. Standard bushing mounted circuit breakers shall have no designator. P - Cover-plate mount. 2.
