What is BS EN 4838-001 - Arc fault circuit breakers about ?
BS EN 4838-001 is a European standard that specifies the single-pole temperature compensated arc fault circuit breakers with or without signal contacts, rated from 3 A to 25 A and used in aircraft on-board circuits. In any operating state, "trip-free" tripping is ensured. These items are designed to protect aircraft wiring systems from circuit overload and arc faults. It describes specific environmental, electrical, and mechanical characteristics and the stringency of tests to be applied according to test methods of EN 3841-100.
If the design of the arc fault circuit breakers contains software or complex hardware, as a minimum, the software and hardware shall be developed in accordance with EUROCAE ED-12B or C / RTCA DO-178B or C, DAL C, and EUROCAE ED-80 / RTCA DO-254, DAL C, respectively.
These arc fault circuit breakers are intended for use in aircraft with electrical supplies in accordance with EN 2282.
