Seritë e hapësirës ajrore - Ndërprerës qarku, me tre pole, temperaturë e kompensuar, rrymë nominale 1 A deri 25 A - Pjesa 004: Pjesë fundore të filetuara UNC - Standard produkti
Aerospace series - Circuit breakers, three-pole, temperature compensated, rated currents 1 A to 25 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 1 A to 25 A, used in aircraft on-board circuits at a temperature between − 55 °C and 125 °C for ratings ≤ 15 A and − 55 °C to 90 °C 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.
