DESCRIPTION

BS EN 4838-005:2019


This standard BS EN 4838-005:2019 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 is classified in these ICS categories:
  • 49.060 Aerospace electric equipment and systems
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 circuit breaker 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.
