18、5 C and 90 C at an altitude of 15 000 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. 2 Normative references The following documents, in whole or in p
