Aerospace series - Circuit breakers, single-pole, temperature compensated, rated current 20 A to 50 A - Part 001: Technical specification

This standard specifies the single-pole temperature compensated circuit breakers with signal contacts, polarized or not, rated from 20 A to 50 A and used in aircraft on-board circuits. It describes specific environmental, electrical and mechanical characteristics and the stringency of tests to be applied according to test methods of EN 3841-100.
These circuit breakers are intended for use in aircraft with electrical supplies in accordance with EN 2282 (all categories).

Luft- und Raumfahrt - Schutzschalter, einpolig, temperaturkompensiert, Nennströme von 20 A bis 50 A - Teil 001: Technische Lieferbedingungen

Diese Norm legt einpolige, temperaturkompensierte Schutzschalter mit Signalkontakten, polarisiert oder nicht, Nennströme von 20 A bis 50 A, für den Einsatz in Luftfahrzeug Bordnetzen fest. Sie beschreibt die spezifi¬schen Umwelt , elektrischen und mechanischen Eigenschaften und den Umfang der entsprechend den Prüf¬verfahren nach EN 3841 100 durchzuführenden Prüfungen.
Diese Schutzschalter sind für den Einsatz in Luftfahrzeugen mit Stromversorgung nach EN 2282 (alle Katego¬rien) vorgesehen.
