Low-voltage switchgear and controlgear - Part 6-2: Multiple function equipment - Control and protective switching devices (or equipment) (CPS) (IEC 60947-6-2:2020 + COR1:2021)

Applies to control and protective switching devices (or equipment) (CPS), the main contacts of which are intended to be connected to circuits of rated voltage not exceeding 1 000 V a.c. or 1 500 V d.c. CPSs are intended to provide both protective and control functions for circuits and are operated otherwise than by hand. They may also fulfil additional functions, such as isolation.

Appareillage à basse tension - Partie 6-2: Matériels à fonctions multiples - Appareils (ou matériel) de connexion de commande de protection (ACP) (IEC 60947-6-2:2020 + COR1:2021)

Est applicable aux appareils (ou aux matériels) de connexion de commande et de protection (ACP), dont les contacts principaux sont destinés à être reliés à des circuits dont la tension assignée n'est pas supérieure a 1 000 V en courant alternatif ou 1 500 V en courant continu. Les ACP sont destinés à assurer à la fois les fonctions de commande et de protection et peuvent aussi assurer des fonctions complémentaires telles que le sectionnement.

Nizkonapetostne stikalne in krmilne naprave - 6-2. del: Večfunkcijska oprema - Krmilne in zaščitne stikalne naprave (ali oprema) (CPS) (IEC 60947-6-2:2020 + COR1:2021)

Uporablja se za krmilne in zaščitne stikalne naprave (ali opremo) (CPS), katerih glavni kontakti so namenjeni za povezavo s tokokrogi, katerih nazivna napetost ne presega 1000 V izmenične ali 1500 V enosmerne napetosti. Centralni napajalni sistemi so namenjeni za zagotavljanje tako zaščitnih kot nadzornih funkcij za tokokroge in se jih ne upravlja ročno. Prav tako lahko opravljajo dodatne funkcije, kot je izolacija.
