Aerospace series. Circuit breakers, three-pole, temperature compensated, rated current 20 A to 50 A - UNC thread terminals. Product standard1 Scope This European Standard 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.
