This document specifies the characteristics of three-pole circuit breakers, temperature compensated with a rated current from 20 A to 50 A, used in aircraft on-board circuits at a temperature between −55 °C and 90 °C at an altitude of 15 000 m max.
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.
