Scope

This document specifies the characteristics of single-pole circuit breakers, temperature compensated with a rated current from 20 A to 25 A, used in aircraft on-board circuits at a temperature between −55 °C and 125 °C and at an altitude of 15 000 m max.
These circuit breakers are operated by a push-pull type single push button (actuator), with delayed action “trip-free” tripping.
They will continue to function up to the short-circuit current.
