Low-voltage switchgear and controlgear - Part 4-3: Contactors and motor-starters - AC semiconductor controllers and contactors for non-motor loads

IEC 60947-4-3:2014 applies to a.c. semiconductor non-motor load controllers and contactors intended for performing electrical operations by changing the state of a.c. electric circuits between the ON-state and the OFF-state. Typical applications are classified by utilization categories given in Table 2. This second edition cancels and replaces the first edition published in 1999, Amendment 1:2006 and Amendment 2:2011. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) Update of the marking requirements (6.1); b) Update of the EMC requirements (8.3.2); and c) Update of the tests requirements (9.3.1, 9.4, 9.4.1.1, 9.4.1.2, 9.4.2.1, 9.4.2.2, 9.4.2.3, 9.4.2.4, 9.4.2.6).

Appareillage à basse tension - Partie 4-3: Contacteurs et démarreurs de moteurs - Gradateurs et contacteurs à semiconducteurs pour charges, autres que des moteurs, à courant alternatif

L'IEC 60947-4-3:2014 s'applique aux gradateurs et démarreurs à semiconducteurs à courant alternatif pour des charges autres que des moteurs prévus pour effectuer des man uvres électriques en changeant l'état des circuits électriques à courant alternatif entre l'état passant et l'état bloqué. Des applications typiques classées par catégorie d'emploi sont données au Tableau 2. Cette deuxième édition annule et remplace la première édition parue en 1999, l'Amendement 1:2006 et l'Amendement 2:2011. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: a) mise à jour des exigences de marquage (6.1); b) mise à jour des exigences de CEM (8.3.2); et c) mise à jour des exigences d'essais (9.3.1, 9.4, 9.4.1.1, 9.4.1.2, 9.4.2.1, 9.4.2.2, 9.4.2.3, 9.4.2.4, 9.4.2.6).

Nizkonapetostne stikalne in krmilne naprave - 4-3. del: Kontaktorji in motorski zaganjalniki, polprevodniški krmilniki in kontaktorji na izmenični tok za nemotorske obremenitve (IEC 60947-4-3:2014)

Standard EN IEC 60947-4-3 se uporablja za polprevodniške krmilnike in kontaktorje na izmenični tok za nemotorske obremenitve, namenjene izvajanju električnih operacij s spreminjanjem stanja izmeničnih električnih tokokrogov med stanjem vključenosti in izključenosti. Običajne uporabe se razvrščajo po kategorijah uporabe iz tabele 2. Kot krmilniki se lahko uporabljajo za zmanjšanje amplitude efektivne izmenične napetosti na bremenskih spojkah glede na amplitudo uporabljene napetosti, in sicer trajno ali za določeno obdobje. Obdobje polovičnega vala izmenične valovne oblike ostaja nespremenjeno glede na obdobje uporabljene napetosti. Vključujejo lahko serijsko mehansko stikalno napravo in so namenjeni priključku na tokokroge z naznačeno izmenično napetostjo, ki ne presega 1000 V. Ta standard opisuje krmilnike in kontaktorje za uporabo z obvodnimi stikalnimi napravami ali brez njih. Polprevodniški krmilniki in kontaktorji, obravnavani v tem standardu, običajno niso namenjeni prekinitvi kratkostičnih tokov. Zato naj bi bila ustrezna zaščita pred kratkim stikom (glej točko 8.2.5) del inštalacije, vendar ne nujno tudi del samega krmilnika. V tem okviru ta standard določa zahteve za polprevodniške krmilnike in kontaktorje, povezane z ločenimi napravami za zaščito pred kratkim stikom.
