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.
Benefits: Transformer protection (50 kVA, 100 kVA or 160 kVA) more compact and easier to use than a fused solution
When the Circuit Breaker is closed, a spark gap limits the rise in potential of the LV neutral from the earth, for a value exceeding 10 kV
When the Circuit Breaker is open, an electrical connection is done between the neutral of the transformer and the groundContact us to define your needs (number of feeders, fixing support, type of rod assembly, Trip Unit type, Load Indicator option, etc.)

Benefits
1. Transformer protection (50 kVA, 100 kVA or 160 kVA) more compact and easier to use than a fused solution
2. When the Circuit Breaker is closed, a spark gap limits the rise in potential of the LV neutral from the earth, for a value exceeding 10 kV
3. When the Circuit Breaker is open, an electrical connection is done between the neutral of the transformer and the ground
