Aerospace series - Circuit breakers, three-pole, temperature compensated, rated currents 2 A to 25 A, switching capacity 65 /n - Part 004: UNC thread terminals - Product standard
This standard specifies the required characteristics for three-pole, temperature compensated circuit breakers, rated currents from 2 A to 25 A, switching capacity 65 In, UNC thread terminals, for use in aircraft electrical systems. Their oprating temperatures are between -55°C and 125°C for rated currents equal or lower than 15 A and between -55°C and 90°C for rated currents higher than 15 A, at amaximum altitude of Z = 22 000 m. It shall be used together with EN 3774-001. These circuit breakers are intended for use in aircraft with electrical supplies in accordance with EN 2282.
Luft- und Raumfahrt - Schutzschalter, dreipolig, temperaturkompensiert, Nennströme von 2 A bis 25 A, Schaltvermögen 65 /n - Teil 004: UNC-Klemmengewinde - Produktnorm
Diese Norm legt die Anforderungen an temperaturkompensierte, dreipolige Schutzschalter mit Nennströmen von 2A bis 25A, Schaltvermögen 65 In, mit UNC-Klemmengewinde, für den Einsatz in elektrischen Bordnetzen fest. Ihre Betriebstemperaturen liegen zwischen -55 °C und 125 °C für Nennströme, die kleiner oder gleich 15 A sind und zwischen -55 °C und 90 °C für Nennströme, die größer als 15 A sind, bis zu einer Höhe von Z = 22 000 m. Sie ist in Verbindung mit EN 3774-001 anzuwenden. Diese Schutzschalter sind zum Einsatz in Luftfahrzeugen mit elektrischer Stromversorgung nach EN 2282 bestimmt.
Série aérospatiale - Disjoncteurs tripolaires compensés en température, intensités nominales 2 A à 25 A, pouvoir de coupure 65 /n - Partie 004: Bornes à filetage UNC - Norme de produit
La présente norme spécifie les caractéristiques requises des disjoncteurs tripolaires compensés en température, d'intensités nominales 2 A à 25 A, pouvoir de coupure 65 In, bornes à filetage UNC, utilisés dans les circuits électriques à bord d'aéronefs. Leurs températures de fonctionnement sont comprises entre -55 °C et 125 °C pour les intensités nominales égales ou inférieures à 15 A et entre -55°C et 90 °C pour les intensités nominales supérieures à 15 A, à une altitude Z = 22000 m. Elle doit être utilisée conjointement avec EN 3774-001.
