Product descriptions from the supplier
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.

Consulting
Q: What pole configuration do LV pole-mounted Circuit breakers adopt?
A:
LV pole-mounted Circuit breakers are four-pole devices, among which three poles are equipped with protection functions to meet the protection needs of MV/LV transformers.
Q: What arc interruption technology do LV pole-mounted Circuit breakers use?
A: They adopt air-break technology, with chambers equipped with metal partitions to effectively cut the arc and ensure stable interruption performance.
Q: Why are LV pole-mounted Circuit breakers suitable for rural power grids?
A: Rural power grids often have significant load imbalances. LV pole-mounted Circuit breakers are specially adapted to this characteristic, ensuring the total use of installed power while protecting MV/LV transformers.
