Low-voltage switchgear and controlgear - Part 3: Switches, disconnectors, switch-disconnectors and fuse-combination units (IEC 60947-3:2008)

IEC 60947-3:2008 applies to switches, disconnectors, switch-disconnectors and fuse-combination units to be used in distribution circuits and motor circuits of which the rated voltage does not exceed 1 000 V a.c. or 1 500 V d.c. This part does not apply to equipment coming within the scope of IEC 60947-2, IEC 60947-4-1 and IEC 60947-5-1; however, when switches and fuse-combination units coming into the scope of this part are normally used to start, accelerate and/or stop an individual motor they shall also comply with the additional requirements given in Annex A. The requirements for single pole operated three pole switches are included in Annex C. Auxiliary switches fitted to equipment within the scope of this part shall comply with the requirements of IEC 60947-5-1. This part does not include the additional requirements necessary for electrical apparatus for explosive gas atmospheres. This edition includes the following significant technical changes with respect to the previous edition:  - alignment with the fifth edition of IEC 60947-1;  - a switching operation without current allowed between making and breaking operation (Table 3);  - increased number of operations for AC-23 allowed with agreement of the manufacturer (Table 3);  - simplified test procedure amended, f) added to 8.3.2.1.3;  - temperature rise test shall be made at the rated operational current /e instead of the conventional enclosed thermal current /the (8.3.3.1).

Appareillage à basse tension - Partie 3: Interrupteurs, sectionneurs, interrupteurs-sectionneurs et combinés-fusibles (CEI 60947-3:2008)

La CEI 60947-3:2008 s'applique à l'appareillage suivant: interrupteurs, sectionneurs, interrupteurs-sectionneurs et combinés-fusibles, destinés à être insérés dans des circuits de distribution et des circuits de moteurs dont la tension assignée est inférieure ou égale à 1 000 V en courant alternatif ou à 1 500 V en courant continu. La présente partie n'est pas applicable au matériel faisant partie du domaine d'application de la CEI 60947-2, de la CEI 60947-4-1 et de la CEI 60947-5-1; cependant, quand les interrupteurs et les combinés-fusibles faisant partie du domaine d'application de la présente partie sont normalement utilisés pour assurer le démarrage, l'accélération et/ou l'arrêt d'un moteur, ils doivent aussi répondre aux exigences supplémentaires figurant à l'Annexe A. Les exigences pour les interrupteurs tripolaires à commande unipolaire se trouvent à l'Annexe C. Les interrupteurs auxiliaires montés sur du matériel faisant partie du domaine d'application de la présente partie doivent satisfaire aux exigences de la CEI 60947-5-1. La présente partie ne contient pas les exigences supplémentaires nécessaires au matériel électrique pour atmosphères explosives. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:  - alignement avec la cinquième édition de la CEI 60947-1;  - une manoeuvre de commutation sans courant est admise entre une manoeuvre d'établissement et de coupure (Tableau 3);  - un nombre accru de manoeuvres pour AC-23 est admis avec l'accord du fabricant (Tableau 3);  - la procédure d'essai simplifiée est corrigée, le point f) a été ajouté en 8.3.2.1.3;  - l'essai d'échauffement doit être réalisé au courant assigné d'emploi /e au lieu du courant thermique conventionnel sous enveloppe /the (8.3.3.1).

Nizkonapetostne stikalne in krmilne naprave - 3. del: Stikala, ločilniki, ločilna stikala in stikalni aparati z varovalkami (IEC 60947-3:2008)

Ta del standarda IEC 60947 se uporablja za stikala, ločilnike, ločilna stikala in stikalne aparate z varovalkami, ki so namenjeni uporabi v razdelilnih tokokrogih in motorskih tokokrogih, pri čemer nazivna napetost ne presega 1000 V izmenične napetosti ali 1500 V enosmerne napetosti. Proizvajalec mora določiti vrsto, mejne vrednosti in značilnosti vseh vključenih varovalk v skladu z ustreznim standardom. Ta del se ne uporablja za opremo, ki spada v področje uporabe standardov IEC 60947-2, IEC 60947-4-1 in IEC 60947-5-1; vendar morajo biti stikala in stikalni aparati z varovalkami, ki bodo spadali v področje uporabe tega dela in se običajno uporabljajo za zagon, pospeševanje in/ali ustavljanje posameznega motorja, prav tako skladni z dodatnimi zahtevami iz dodatka A. Zahteve za tripolna stikala z enim samim priključnim polom so zajete v dodatku C. Pomožna stikala, pritrjena na opremo, ki spada v področje uporabe tega dela, morajo biti skladna z zahtevami standarda IEC 60947-5-1. Ta del ne zajema dodatnih zahtev, potrebnih za električne naprave za eksplozivne plinske atmosfere.
