EN 4839-001:2018

Aerospace series - Arc fault circuit breakers, three-poles, temperature compensated, rated current 3 A to 25 A - 115 V a.c. 400 Hz constant frequency - Part 001: Technical specification

This European 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.

Aeronavtika - Obločni dušilni odklopniki, tripolni, temperaturno kompenzirani, za naznačene toke od 3 A do 25 A - 115 V izmenična napetost, 400 Hz konstantna frekvenca - 001. del: Tehnična specifikacija

Ta evropski standard določa tripolne, temperaturno kompenzirane obločne dušilne odklopnike brez signalnih kontaktov in z nazivnim tokom od 3 A do 25 A, ki se uporabljajo v letalskih vezjih. V vseh delovnih stanjih je zagotovljeno proženje brez sprožila. Ti elementi so zasnovani tako, da letalsko vezje varujejo pred preobremenitvijo in obloki. Opisuje posebne okoljske, električne in mehanske lastnosti ter strogost preskusov, ki se uporabljajo v skladu s preskusnimi metodami iz standarda EN 3841-100.
Če zasnova obločnih dušilnih odklopnikov zajema programsko opremo ali zahtevno strojno opremo, so minimalne zahteve takšne,
da mora biti tovrstna oprema razvita v skladu z določili RTCA DO-178B ali C, DAL C in RTCA DO-254, DAL C, kot je ustrezno.
Ti odklopniki so namenjeni uporabi v letalskih plovilih z električno oskrbo v skladu s standardom EN 2282.
