9、this standard has received approval for Publication. prEN 3773-006:2015 (E) 3 1 Scope This standard 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

10、 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. They will continue to function up to the short-circuit current. 2 Normative references The following documents, in whole or in part, a
