Seritë e hapësirës ajrore - Stakuesit e qarkut, tri polësh, për temperaturë të balancuar, me rrymë elektrike nominale 20 A deri në 50 A - Pjesa 004: Pjesët fundore të filetuara UNC - Standard produkti
Aerospace series - Circuit breakers, three-pole, temperature compensated, rated current 20 A to 50 A - Part 004: UNC thread terminals - Product standard
This European 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 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.
