High-voltage switchgear and controlgear - Part 105: Alternating current switch-fuse combinations IEC 62271-105:2002 ED1

Publication date:   Aug 22, 2002

Scope

Applies to three-pole units for public and industrial distribution systems which are functional assemblies of switches including switch-disconnectors and current-limiting fuses designed so as to be capable of
- breaking, at the rated recovery voltage, any 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.
It does not apply to fuse-circuit-breakers, fuse-contactors, combinations for motor-circuits or to combinations incorporatingsingle capacitor bank switches.
