Their function is assured up to the short-circuit current. 5 De

27、sign 5.1 Materials 5.1.1 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

28、0,25 V. When bimetals 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 fir

29、e or internal electric arc. They shall be insensitive to moulds and micro-organisms action. Application of any material or protective coating, which might crack, break or flake shall be forbidden. Materials which are not specified or which are not specially described shall be as light as possible fo

30、r the requested use. Materials 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 De

31、sign of circuit breaker 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.

32、The operation in these conditions shall not affect further performances of the circuit breaker. 5.2.3 Attachment All visible parts shall be black coloured and non-reflective. 5.2.4 Electrical connection units They shall be able to receive the lugs (or contacts).

In disengaged (or opened) position, the control actuator shall show a white strip. The o

34、uter part of this actuator shall be isolated from all undervoltage parts. The control actuator shall not 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 and indicat

35、ing contact opens. When pulling it, power contacts of the circuit breaker open and indicating contact closes. The circuit breaker rating is indicated in indelible white colour on the front part of the control actuator. The product standard gives the digits positioning. 5.2.6 Rating inviolability The

36、 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 the minimal space to be foreseen between the undervoltage parts and any other part of the circuit breaker made of non-insulating material

37、, as well as between the undervoltage parts of opposite polarity, shall be sufficient to avoid any default or arc tracking in all uses and climatic conditions. 5.2.8 Protection against non-release Electrical overload happening on a circuit breaker locked in its engaged position (sticked contacts or

38、non-operating release mechanism), shall cause the opening of the circuit by circuit breaker destruction without any fire or important smoke release. 6 Characteristics 6.1 General characteristics See Table 1.
