UNE-EN IEC 62271-200:2021

This part of IEC 62271 is applicable to prefabricated metal-enclosed switchgear and

controlgear assemblies designed:

for alternating current;

with rated voltages above 1 kV and up to and including 52 kV;

for service frequencies from 16 2/3 Hz up to and including 60 Hz;

for indoor and outdoor installation;

It may include fluid-filled compartments, either with design pressure lower than or equal to

300 kPa (relative pressure) or designed and tested to the pressure withstand requirements of

IEC 62271-203.

For components installed in a metal-enclosed switchgear and controlgear, this standard

supplements or even replaces in some cases, the requirements as stated by the individual

product standards.

The list of components which may be inside the metal-enclosed switchgear and controlgear is

not limited to the ones explicitly cited in this standard.
