Product Details
The protection and management of MV/LV transformers in rural areas requires the use of specific circuit breakers adapted to significant load imbalances, thus ensuring the full utilization of installed power even under imbalance conditions. These low voltage pole mounted circuit breakers (4 poles – 3 protected) use air-break technology with metal-partitioned chambers to interrupt the arc.
Benefits
1. Transformer protection (50 kVA or 100 kVA) is more compact and simpler to use than a fuse-based solution.
2. When the low voltage pole mounted circuit breaker is closed, a spark gap limits the potential rise of the low-voltage neutral relative to earth, for a value greater than 10 kV
3. When low voltage pole mounted circuit breakers is open, an electrical connection is made between the transformer neutral and earth.
4. Contact us to define your needs (number of starting points, mounting bracket, linkage type, trigger type, load indicator option, etc.)
