4、of Europe - Standardization). It is published for the needs of the European Aerospace Industry. It has been technically approved by the experts of the concerned Domain following member comments. Subsequent to the publication of this Prestandard, the technical content shall not be changed to an exten

After examination and review by users and formal agreement of ASD-STAN, it will be submitted as a draft European Standard (prEN) to CEN (European Committee for Standardization) for formal vo
6、te and transformation to full European Standard (EN). The CEN national members have then to implement the EN at national level by giving the EN the status of a national standard and by withdrawing any national standards conflicting with the EN.

After inquiries and votes carried out in accordance with the rules of ASD-STAN defined in ASD-STANs General Process Manual,
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
