BS EN 2665-001:2013EN 2665-001:2013 (E) 4 1 Scope This European Standard specifies the three-pole temperature compensated circuit breakers without signal contacts, rated from 20 A to 50 A and used in aircraft on-board circuits. It describes specific environmental, electrical and

18、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 supplies in accordance with EN 2282. 2 Normative references The following documents, in whole or in part, are normati

25、1.1 Metallic materials All metallic parts shall 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

26、 are used, an eventual corrosion shall not affect 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 electri

27、c arc. They shall be insensitive to moulds and microorganisms 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. M

28、aterials shall be selected according to security 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 breake

29、r mechanism shall allow free release; i.e. the circuit breaker cuts out in case of overload, and remains cut out even if the actuator is kept by force in engaged position. A new engagement of circuit breaker is only possible after a first total release of the control actuator. The operation in these

30、 conditions shall not affect further performances of the circuit breaker. 5.2.3 Attachment All visible parts shall be black colored and non-reflective. 5.2.4 Electrical connection units They shall be able to receive the lugs. 5.2.5 Control actuator In engaged position, the visible part of the contro

31、l actuator shall be of the colour stated in the product standard. In disengaged (or opened) position, the control actuator shall show a white strip. The outer part of this actuator shall be isolated from all under voltage parts. BS EN 2665-001:2013EN 2665-001:2013 (E) 6 The control actuator shall no

32、t stay in a transition position, or give a false indication about the circuit breaker condition. It shall not be removable. When pushing it, power contacts of the circuit breaker engage. When pulling it, power contacts of the circuit breaker open. The circuit breaker rating is indicated in indelible

33、 white colour on the front part of the control actuator. The product standard gives the digits positioning. 5.2.6 Rating inviolability The circuit breaker shall be designed in such a way that the calibration unit cannot be reached without breaking a sealing. 5.2.7 Leakage lines The leakage lines and

34、 the minimal space to be foreseen between the under voltage parts and any other part of the circuit breaker made of non-insulating material, as well as between the under voltage parts of opposite polarity, shall be sufficient to avoid any default or arcing in all uses and climatic conditions. 5.2.8

35、Protection against non-release Electrical overload happening on a circuit breaker locked in its engaged position (sticked contacts or non-operating release mechanism), shall cause the opening of the circuit by circuit breaker destruction without any fire or important smoke release. 6 Characteristic
