This part of IEC 60947 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.
The manufacturer shall specify the type, ratings and characteristics according to the relevant
standard of any incorporated fuses.
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.dition 3.2 2015-07 CONSOLIDATED VERSION VERSION CONSOLIDéE colour inside Low-voltage switchgear and controlgear – Part 3: Switches, disconnectors, switch-disconnectors and fuse-combination units Appareillage à basse tension – Partie 3: Interrupteurs, sectionneurs, interrupteurs-sectionneurs et combinés- fusibles IEC 60947-3:2008-08+AMD1:2012-02+AMD2:2015-07 CSV(en-fr) THIS PUBLICATION IS COPYRIGHT PROTECTED Copyright ？
