24、andard 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
25、single push button (actuator), with delayed action “trip-free“ tripping. They will continue to function up to the short-circuit current. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
