- Exclusive use in Counter Centralizations with CMM-SGC and CMT-SGC type measuring columns that do not supply Generation, Storage or Recharge systems and that do NOT require Transient Surge Protection: they are powered by an entirely underground network, installed in Farms more than 50 meters from any lightning conductor, located in provinces with less than 20 stormy days per year according to Map A of the ITC-BT-23 Guide and in which no supply meets any of the situations or risks indicated in Tables A and B of the ITC-BT-23 Guide.
- Intensities of the 4-pole load break switch with advanced IGM neutral: 160A, 250A and 400A *.
* IGM 400 A: Exceptional use in centralizations made up of several measuring columns whose horizontal busbars are dimensionedfor a maximum intensity of 400 A.
