Aerospace series - Arc fault circuit breakers, single-pole, temperature compensated, rated current 3 A to 25 A - 115 V a.c. 400 Hz constant frequency - Part 004: With signal contact - Product standard

This European Standard specifies the required characteristics for single-pole, arc fault circuit breakers rated currents from 3 A to 25 A, switching capacity 65 In, for use in aircraft electrical systems. Their operating temperatures are between  40 °C to 85 °C at a maximum altitude of Z = 15 000 m. The thermal protection is temperature compensated and operates between  55 °C and 125 °C.
These arc fault 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.

Série aérospatiale - Disjoncteurs unipolaires à détection d’arc compensés en température, intensités nominales 3 A à 25 A - 115 V c.a. 400 Hz fréquence fixe - Partie 004 : Avec contact de signalisation - Norme de produit

La présente Norme européenne spécifie les caractéristiques requises pour les disjoncteurs unipolaires à détection d’arc d’intensités nominales 3 A à 25 A, capacité de coupure 65 In, destinés à être utilisés dans les systèmes électriques des aéronefs. Leurs températures de fonctionnement sont comprises entre  40 °C et 85 °C à une altitude maximale de Z = 15 000 m. La protection thermique est compensée en température et fonctionne entre  55 °C et 125 °C.
Ces disjoncteurs à détection d’arc sont activés par un bouton poussoir unique (bouton de commande), à déclenchement libre temporisé.
Leur fonctionnement est assuré jusqu’au courant de court-circuit.

Aeronavtika - Obločni dušilni odklopniki, enopolni, temperaturno kompenzirani, za naznačene toke od 3 A do 25 A , 115 V izmenična napetost 400 Hz konstantna frekvenca - 004. del: S signalnim kontaktom - Standard za proizvod

Ta evropski standard določa potrebne lastnosti obločnih dušilnih odklopnikov, enopolnih, temperaturno kompenziranih, za naznačene toke od 3 A do 25 A, s preklopno zmogljivostjo 65 In, za uporabo v letalskih električnih sistemih. Njihove obratovalne temperature so od 40 °C do 85 °C pri maksimalni višini Z = 15 000 m. Toplotna zaščita je temperaturno kompenzirana in obratuje pri temperaturah od  55 °C do 125 °C.
Ti obločni dušilni odklopniki se upravljajo z enim gumbom (sprožilom) vrste potisni-povleci, z zakasnjenim proženjem brez sprožila.
Delovali bodo do kratkega stika.
