scope:
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 In, for use in aircraft electrical systems. Their operating temperatures are between − 40 °C to 85 °C at a maximum altitude of Z = 15 000 m. The thermal protection is temperature compensated and operates between − 55 °C and 125 °C.
These arc fault circuit breakers are operated by a push-pull type single pushbutton (actuator), with delayed action "trip-free" tripping.
They will continue to function up to the short-circuit current.
