11、d from 20 A to 50 A and used in aircraft on-board circuits. It describes specific environmental, electrical and mechanical characteristics and the stringency of tests to be applied according to test methods of EN 3841-100. These circuit breakers are intended for use in aircraft with electrical suppl

20、 in EN 3841-100 apply. 4 Description These circuit breakers are operated by a “push-pull“ type single pushbutton (actuator) and with delayed action “trip-free“ tripping. Their function is assured up to the short-circuit current. 5 Design 5.1 Materials 5.1.1 Metallic materials All metallic parts shal
21、l be resistant to corrosion or finished against corrosion. When dissimilar materials are in close contact, an adequate protection against corrosion shall be used so that the electromotive force of the galvanic couple does not exceed 0,25 V. When bimetals are used, an eventual corrosion shall not aff
22、ect the good operation of the circuit breaker. 5.1.2 Insulation materials The insulating parts shall be made of auto-extinguishing or non-flammable materials; they shall not emit damaging or explosive vapours, even in presence of fire or internal electric arc. They shall be insensitive to moulds and
23、 micro-organisms action. Application of any material or protective coating, which might crack, break on flake shall be forbidden. Materials which are not specified or which are not specially described shall be as light as possible for the requested use. Materials shall be selected according to secur
24、ity criteria (toxicity, smoke density) as defined in contractual documents. 5.2 Design 5.2.1 Insulating box The insulating box shall integrate besides the mechanism, the connection and attachment unit. 5.2.2 Free release mechanism Design of circuit breaker mechanism shall allow free release; i.e. th
