5. Title, number of pages  and language(s)  of the notified document:  BOS IEC 60947 -3, 
Low-voltage switchgear and controlgear - Part 3: Switches, disconnectors, switch -
disconnectors and fuse -combination units (284 pages, in English).     
6. Description of content:  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 e xceed 1000 V a.c. or 1500 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 req uirements 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.  
NOTE 1 Depending on its design, a switch (or disconnector) can be referred to as a rotary 
switch (disconnector), cam -operated switch (disconnector), knife -switch (disconnector), 
etc. G/TBT/N/BWA/59

  NOTE 2  In this part, the word switch also applies to the apparatus referred to in French as 
commutateurs, intended to modify the connections between several circuits and inter alia 
to substitute a part of a circuit for another.  
NOTE 3 In general, throughout this  part switches, disconnectors, switch -disconnectors and 
fuse-combinatio n units will be referred to as equipment.  
The object of this part is to state  
 the characteristics of the equipment;  
 the conditions with which the equipment shall comply with reference t o  
 operation and behaviour in normal service;  
 operation and behaviour in case of specified abnormal conditions, e.g. short 
circuit;  
 dielectric properties;  
 the tests for confirming that these conditions have been met and the 
methods to be adopted for these tests;  
 the information to be marked on the equipment or made available by the 
manufacturer, e.g. in the catalogue.  
7. Objective and rationale , including the nature of urgent problems where applicable:  
Quality requirements ; Prevention of deceptive practice s and consumer protection
