适用范围

"This standard specifies the three-poles temperature compensated arc fault circuit breakers without signal contacts@ rated from 3 A to 25 A and used in aircraft on-board circuits. In any operating state a ""trip-free"" tripping is ensured. These Items are designed to protect aircraft wiring system 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 RTCA DO-178B or C@ DAL C and RTCA DO-254@ DAL C@ respectively. These circuit breakers are intended for use in aircraft with electrical supplies in accordance with EN 2282."
