This document specifies the characteristics of single-pole circuit breakers, temperature compensated with a rated current from 1 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 with a polarized signal contact which is open when main contacts are closed, and inversely. They will continue to function up to the short-circuit current.
