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of an identical text or by endorsement, at the latest by February 2007, and conflicting national standards shall be withdrawn at the latest by February 2007.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 is dra

EN 3662-006:20064 1 Scope This 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 and at an altit
18、ude 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-bar. They
19、 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.
