EN 60420:1993
(Main)High-voltage alternating current switch-fuse combinations
High-voltage alternating current switch-fuse combinations
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 fuses and thus able to interrupt: -any load current up to the rated breaking current of the switch; -any over-current up to the rated short-circuit breaking current of the combination by which automatic interruption is initiated. This standard applies to combinations designed with rated voltages above 1 kV and below 52 kV for use on three-phase alternating current systems of either 50 Hz or 60 Hz.
Hochspannungs-Latschalter-Sicherungs-Kombination
Combinés interrupteurs-fusibles à haute tension pour courant alternatif
S'applique aux appareils tripolaires utilisés dans les réseaux de distribution publics ou les installations industrielles, appareils formant des ensembles fonctionnels composés d'interrupteurs ou d'interrupteurs-sectionneurs et de fusibles limiteurs de courant, et ainsi capables d'interrompre: - tout courant de charge jusqu'au pouvoir de coupure assigné de l'interrupteur; - toute surintensité jusqu'au pouvoir de coupure assignée du combiné et qui provoque une interruption automatique. S'applique aux combinés prévus pour des tensions assignées supérieures à 1 kV et inférieures à 52 kV, et destinés à être utilisés sur des réseaux triphasés à courant alternatif à 50 Hz ou 60 Hz.
