Advantage
The protection and management of MV / LV transformers in rural areas requires the use of specific Circuit Breakers adapted to significant load imbalances and thus guarantees the total use of the installed power even in unbalanced conditions. These devices (4 poles - 3 protected) use air-break technology with chambers with metal partitions to cut the arc.
