This European Standard specifies the characteristics of three-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 \u00b0C and 125 \u00b0C for ratings ? 15 A and ? 55 \u00b0C to 90 \u00b0C for ratings > 15 A and at an altitude of 22 000 m max. These circuit breakers are operated by a push-pull type single pushbutton (actuator), with delayed action ‘trip-free’ tripping. They will continue to function up to the short-circuit current.<\/p>\n
