Aerospace series - Circuit breakers, three-poles, temperature compensated, rated currents 1 A to 25 A - Part 006: 6,3 & 2,8 mm blade terminal - With polarized signal contact - Product standard

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.

Série aérospatiale - Disjoncteurs tripolaires compensés en température, intensités nominales 1 A à 25 A - Partie 06 : Raccordement par lame 6,3 & 2,8 mm - Avec contact auxiliaires polarisés - Norme de produit

Le présent document spécifie les caractéristiques des disjoncteurs tripolaires compensés en température à intensité nominale de 1 A à 25 A, utilisés dans les circuits embarqués des aéronefs à des températures comprises entre -55 °C et 125 °C pour des intensités ≤ 15 A, et de -55 °C à 90 °C pour des intensités  > 15 A, à une altitude de 15 000 m max.
Ces disjoncteurs sont commandés par un bouton poussoir unique (bouton de commande) de type « push pull », à déclenchement libre temporisé.
Leur fonctionnement est assuré jusqu’au courant de court-circuit.
