19、rcraft on-board circuits at a temperature between 55 C and 125 C and at a maximum altitude of Z = 22 000 m. These circuits 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 contact
20、s are closed, and inversely. 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.
