LV Pole-mounted circuit break Description
The LV Pole-mounted circuit break D265T is a dedicated protection device for rural MV/LV transformer systems, specially engineered to adapt to significant load imbalance scenarios and ensure full utilization of installed power even under unbalanced operating conditions. The D265T circuit break features a 4-pole (3 protected) structure and adopts advanced air-break technology with metal partition arc-extinguishing chambers, which effectively cuts the arc during operation and provides reliable protection for 50 kVA or 100 kVA transformers. Equipped with a digital trip unit, the LV Pole-mounted circuit break D265T realizes precise and intelligent protection control for transformer systems, solving the core pain points of rural power grid transformer protection and management.
D265T circuit break Benefits
- The D265T circuit break offers more compact structure and easier operation for transformer protection compared with traditional fused solutions, simplifying on-site installation and daily maintenance of the LV Pole-mounted circuit break.
- When the D265T circuit break is closed, a built-in spark gap limits the LV neutral potential rise from the earth for values exceeding 10 kV, effectively protecting the transformer and associated power grid equipment from overvoltage damage.
- When the D265T circuit break is open, it automatically establishes an electrical connection between the transformer neutral and the ground, further enhancing the operational safety of the power system where the LV Pole-mounted circuit break is applied.
- Customizable solutions for the LV Pole-mounted circuit break D265T are available—contact us to tailor configurations according to your actual needs, including feeder quantity, fixing support, rod assembly type, trip unit type, load indicator option and more for the D265T circuit break.
