NX2003252 165A Low Voltage Pole Mounted Circuit Breaker Adapted to Significant Load Imbalances

NX2003252 165A Low Voltage Pole Mounted Circuit Breaker Adapted to Significant Load Imbalances

Code: NX2003252
Name: Circuit breaker
Low voltage pole mounted circuit breaker D165T with digital trip unit

Description: 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.
Benefits: Transformer protection (50 kVA or 100 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 ground

Product Description

LV Pole mounted circuit breakers

The protection and management of MV/LV transformers in rural areas requires the use of specific circuit breakers adapted tosignificant load imbalances, and thus guarantees complete power usage even in unbalanced conditions. These devices (4 poles, three of which are protected) use air-break technology with chambers with metal partitions to cut the arc. Low voltage pole mounted circuit breaker D165T - D265T with a digital trip unit.

Benefits

1. Transformer protection (50 kVA or 100 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

4. Contact us to define your needs (number of feeders, fixing support, type of rod assembly, Trip Unit type, Load Indicator option,etc.)
