Aerospace series - Arc Fault Circuit breakers@ three-pole@ temperature compensated@ rated currents 3 A to 25 A@ 115/200 V a.c. 400 Hz constant frequency - Part 003: Without auxiliary contacts - Product standard
"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 ??to 85 ??at a maximum altitude of Z = 15 000 m. The thermal protection is temperature compensated and operates between ? 55 ??and 125 ?? 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."
