Aerospace series Arc Fault Circuit breakers@ single-pole@ temperature compensated@ rated current 3 A to 25 A 115 V a.c. 400 Hz constant frequency Part 005: With polarized signal contact Product standard (Edition P 1)
"This standard specifies the required characteristics for single-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 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."
