This European Standard specifies the required characteristics for three-pole, arc fault circuit breakers, rated currents from 3 A to 25 A, switching capacity 65 I<\/i>n<\/sub>, for use in aircraft electrical systems. Their operating temperatures are between \u2212 40 \u00b0C to 85 \u00b0C at a maximum altitude of Z<\/i> = 15 000 m. The thermal protection is temperature compensated and operates between \u2212 55 \u00b0C and 125 \u00b0C.<\/p>\n

These arc fault circuit breakers are operated by a push-pull type single pushbutton (actuator), with delayed action “trip-free” tripping.<\/p>\n

They will continue to function up to the short-circuit current.<\/p>\n
