The HVD7 40.5KV 1250A VCB is an outdoor vacuum circuit breaker built for three‑phase AC networks at 50 Hz. Its electrical rating is 40.5 kV nominal voltage with a continuous current capacity of 1 250 A. The device is capable of withstanding a one‑minute power‑frequency voltage of 42 kV phase‑to‑phase and 48 kV to ground, in line with IEC 62271‑100 requirements. It can interrupt short‑circuit currents up to 25 kA and tolerate peak fault currents of 63 kA for the duration of the withstand test.
Copper contacts are paired with ceramic or glass vacuum interrupters, while the steel housing receives an anti‑corrosion coating to resist harsh climates. The breaker complies with IEC 62271‑100, the common standard for high‑voltage vacuum switching devices. Typical installations operate within an ambient temperature range of - 30 °C to +40 °C, and the equipment is rated for altitudes up to 2 000 m. Wind pressure resistance is specified at 700 Pa (approximately 34 m s⁻¹), and it is suitable for environments with air‑pollution degree 3 and antifouling class 4.
This VCB is used in substations, power‑plant switchgear and large‑scale industrial facilities that require reliable, low‑maintenance protection. Prospective importers should verify the minimum order quantity, lead time and preferred Incoterm directly with the supplier. Request the IEC 62271‑100 certification and any test reports before finalising purchase.

Before committing to purchase, ask the supplier to provide the IEC 62271‑100 test report and any type‑test certificates that verify the rated voltage, current and short‑circuit performance. Request material data sheets for the copper contacts and the anti‑corrosion coating applied to the steel housing, as these affect long‑term reliability in harsh environments. Having these documents on file helps confirm that the breaker meets the technical requirements of your project.
When planning shipment, clarify the Incoterm - for example CIF or FOB - and agree on payment milestones such as a 30 % upfront deposit followed by balance on sight draft. Because the listing does not state a minimum order quantity or lead time, request those figures together with packaging details, for instance whether the breaker will be packed in a wooden crate or a steel pallet. Early confirmation of logistics reduces the chance of unexpected delays at the destination port.
Upon receipt, arrange a third‑party inspection to verify the external condition of the steel housing, confirm the presence of the vacuum interrupter and test continuity of the copper contacts. Ask the supplier for the factory acceptance test (FAT) report and a certificate of conformity that demonstrates compliance with IEC 62271‑100. Retain all inspection reports, certificates and shipping documents as part of your import compliance records.
