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
"This document 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 breaker 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."
