Overview
This document 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 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. The EN 3774-006 standard has been prepared by the standardization organization ASD-STAN of the AeroSpace and Defence Industries Association of Europe (ASD) with the participation of German experts at DIN Standards Committee Aerospace (NL). The responsible German standardization committee is Working Committee NA 131-04-05 AA "Schalter, Relais und Schutzgeräte" ("Switch, relays and protection devices") at DIN Standards Committee Aerospace (NL).
