High-voltage switchgear and controlgear

Part 107: Alternating current fused circuit-switchers for rated voltages above 1 kV up to and including 52 kV

(IEC 62271-107:2019); German version EN IEC 62271-107:2019
Class/Status: Standard, valid

VDE Art. No.: 0600264

This part of IEC 62271 applies to three-pole operated units for distribution systems that are 239 functional assemblies of a circuit-switcher and current-limiting fuses designed so as to be capable of:
- breaking, at the rated recovery voltage, any load or fault current up to and including the rated short-circuit breaking current;
- making, at the rated voltage, circuits to which the rated short-circuit breaking current applies.
They are intended to be used for circuits or applications requiring only a normal mechanical and electrical endurance capability. Such applications cover protection of HV/LV transformers for instance, but exclude distribution lines or cables, as well as motor circuits and capacitor bank circuits.
