Name:
Circuit breaker Pole Mounted Circuit breaker D265T Middle pole with Digital trip unit
Description:
The protection and management of MV / LV transformers in rural areas require the use of specific Circuit Breakers adapted to significant load imbalances and thus guarantee 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.
