What are the main characteristics for indoor ac medium voltage switches according to IEC 62271-103?

Alternating current switches and switch-disconnectors for their switching function, have making and breaking current ratings, for indoor and outdoor installations, for rated voltages above 1 kV up to and including 52 kV and for rated frequencies from 162/3 Hz up to and including 60 Hz shall follow the IEC 62271-103 standard.
This standard is also applicable to single-pole switches used on three phase systems.

Switch characteristics in common with IEC 62271-1:2011: 
  • rated voltage;
  • rated insulation level;
  • rated frequency;
  • rated normal current and temperature rise;
  • rated short-time withstand current;
  • rated peak withstand current;
  • rated duration of short-circuit;
  • rated supply voltage of closing and opening devices and of auxiliary circuits;
  • rated supply frequency of closing and opening devices and of auxiliary circuits;
  • rated pressures of compressed gas for controlled pressure systems;

Switch characteristics specific to IEC 62271-103:
  • rated filling levels for insulation and/or operation
 - rated filling levels for insulation and/or switching
 - rated filling levels for operation
  • rated mainly active load-breaking current
  • rated closed-loop breaking current
  • rated cable-charging breaking current
  • rated line-charging breaking current
  • rated single capacitor bank breaking current for special purpose switches
  • rated back-to-back capacitor bank breaking current for special purpose switches
  • rated back-to-back capacitor bank inrush making current for special purpose switches
  • rated earth fault breaking current
  • rated cable- and line-charging breaking current under earth fault conditions
  • rated motor breaking current for special purpose switches
  • rated short-circuit making current
  • rated breaking and making currents for a general purpose switch
  • ratings for limited purpose switches
