Aerospace series. Circuit breakers, three-pole, temperature compensated, rated current 1 A to 25 A - With polarized signal contact. Product standard Ingestion-build-202139 – are used at the1 Scope This standard specifies the characteristics of three 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 for ratings 15 A and 55 C and 90 C for ratings > 15 A and at an altitude of 22 000 m max. These circuit breakers are operated by a push pull type single push button (actuator), with delayed action "trip free" tripping with a
