Aerospace series - Arc Fault Circuit breakers, three-pole, temperature compensated, rated currents 3 A to 25 A, 115/200 V a.c. 400 Hz constant frequency - Part 003: Without auxiliary contacts - Product standard

This European Standard specifies the required characteristics for three-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.

SIST EN 4839-003:2018 - Aerospace series - Arc Fault Circuit breakers, three-pole, temperature compensated, rated currents 3 A to 25 A, 115/200 V a.c. 400 Hz constant frequency - Part 003: Without auxiliary contacts - Product standard

Overview

EN 4839-003:2018 is a European product standard in the Aerospace series that specifies required characteristics for three‑pole, temperature‑compensated arc fault circuit breakers (AFCBs) for aircraft electrical systems. Part 003 covers versions without auxiliary contacts, rated for 3 A to 25 A, at 115/200 V a.c., 400 Hz constant frequency. It defines mechanical, electrical and environmental requirements, dimensional constraints, marking, delivery and test references to ensure safe, interchangeable AFCB components for aviation use.
