6. Description of content:   This standard applies to three- pole units for public and industrial 
distribution systems which are functional assemblies of switches including switch-disconnectors and current-limiting fu ses designed to be provided with: 
 
- breaking capability: at the recovery voltage, breaking any current up to and including 
the rated short-circuit breaking current; 
- making capability: at the rate voltage, making circuits to which the rated short-circuit 
breaking current applies. 
- It does not apply to fuse-circuit-breakers,  fuse-contactors combinations for motor-
circuits or  combinations incor porating single capacitor bank switches. 
This standard applies to combinations designe d with nominal voltages above 3 kV up to and 
including 35 Kv, service frequencies up to and including 50Hz used in three-phase alternating current systems for indoor or outdoor installations. 
7. Objective and rationale, including the na ture of urgent problems where applicable:  
To regulate the market and ensure personal safety.
