13、the Aerospace and Defence Industries Association of Europe - Standardization (ASD-STAN). After enquiries and votes carried out in accordance with the rules of this Association, this Standard has received the approval of the National Associations and the Official Services of the member countries of A
14、SD, prior to its presentation to CEN. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by February 2007, and conflicting national standards shall be withdrawn at the latest by February 2007. Attention
15、 is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the
16、following countries are bound to implement this European Standard: Austria, Belgium, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia,
17、 Spain, Sweden, Switzerland and the United Kingdom. EN 3661-006:20064 1 Scope This standard specifies the characteristics of single-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 125 C and at
18、 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 with a polarized signal contact which is open when main contacts are closed, and inversely. They are connected on supply side by means of bus-
19、bar. They will continue to function up to the short-circuit current. 2 Normative references The following referenced documents are indispensable for the application of this document.
