(Amendment)Low-voltage switchgear and controlgear - Part 2: Circuit-breakers
Low-voltage switchgear and controlgear - Part 2: Circuit-breakers
This standard applies to circuit-breakers, the main contacts of which are intended to be connected to circuits, the rated voltage of which does not exceed 1 000 V a.c. or 1 500 V d.c.; it also contains additional requirements for integrally fused circuit-breakers. It applies whatever the rated currents, the method of construction or the proposed applications of the circuit-breakers may be. The requirements for circuit-breakers which are also intended to provide earth-leakage protection are contained in Annex B. The additional requirements for circuit-breakers with electronic over-current protection are contained in Annex F. The additional requirements for circuit-breakers for IT systems are contained in Annex H. The requirements and test methods for electromagnetic compatibility of circuit-breakers are contained in Annex J. The requirements for circuit-breakers not fulfilling the requirements for over-current protection are contained in Annex L. The requirements for modular residual current devices (without integral current breaking device) are contained in Annex M. The requirements and test methods for electromagnetic compatibility of circuit-breaker auxiliaries are contained in Annex N. Supplementary requirements for circuit-breakers used as direct-on-line starters are given in IEC 60947-4-1, applicable to low-voltage contactors and starters. The requirements for circuit-breakers for the protection of wiring installations in buildings and similar applications, and designed for use by uninstructed persons, are contained in IEC 60898. The requirements for circuit-breakers for equipment (for example electrical appliances) are contained in IEC 60934. For certain specific applications (for example traction, rolling mills, marine service) particular or additional requirements may be necessary.

Appareillage à basse tension - Partie 2: Disjoncteurs
Nizkonapetostne stikalne naprave - 2. del: Odklopniki (IEC 60947-2:2006/A1:2009)
Ta standard se uporablja za odklopnike, katerih glavni kontakti so namenjeni za povezavo s tokokrogi, katerih nazivna napetost ne presega 1000 V izmenične ali 1500 V enosmerne napetosti, prav tako pa zajema dodatne zahteve za odklopnike z vgrajeno varovalko. Uporablja se ne glede na nazivne toke, metodo konstrukcije ali predlagano uporabo odklopnikov. Zahteve za odklopnike, ki varujejo pred zemeljskim uhajanjem, zajema dodatek A. Dodatne zahteve za odklopnike z elektronsko zaščito pred nadtokom zajema dodatek F. Dodatne zahteve za odklopnike za sisteme IT zajema dodatek H. Zahteve in preskusne metode za elektromagnetno združljivost odklopnikov zajema dodatek J. Zahteve za odklopnike, ki ne izpolnjujejo zahteve za zaščito pred nadtokom zajema dodatek L. Zahteve za modularne naprave s preostalim tokom (brez vgrajene odklopne naprave) zajema dodatek M. Zahteve in metode preskušanja za elektromagnetno združljivost dodatkov odklopnika zajema dodatek N. Dodatne zahteve za odklopnike, ki se uporabljajo kot neposredni zaganjalniki, so podane v standardu IEC 60947-4-1 ter veljajo za nizkonapetostne kontaktorje in zaganjalnike. Zahteve za odklopnike za zaščito žičnih inštalacij v stavbah ter podobne uporabe in odklopnike, ki jih bodo uporabljale nepoučene osebe, so zajete v standardu IEC 60898. Zahteve za odklopnike za opremo (npr. za električne aparate) so zajete v standardu IEC 60934. Za določene uporabe (npr. vleka, valjarne, storitve v marinah) lahko veljajo posebne ali dodatne zahteve.
