Timetric 630A 3 Phase Vacuum Circuit Breaker Beneficial effect

"630A 3 Phase Vacuum Circuit Breaker" has the advantages of simple structure and large short-circuit current breaking capacity. In the selection of longitudinal magnetic field contacts, reliable short-circuit current breaking can be up to 80 kiloa, and the disc-shaped contact surface is accepted evenly. High insulation strength, in a stable state, vacuum chamber vacuum degree is less than 109 bar, 6-20 mm contact opening is enough to ensure the insulation strength of the vacuum arc extinguishing chamber. The cut-off value is small. By optimizing the cu-Cr material, the average cut-off value is less than 4 am. the contact burn loss is small and the life is long. The contact resistance is small, and the contact material with good conductive performance is used to ensure the minimum contact resistance. The contact resistance value between the two conductive rods in the vacuum arc extinguishing chamber is 8 ~ 15 microohms, so the temperature rise is also low. Vacuum seal is good, using a sealing process, welding quality is reliable and the joint will not aging. High reliability, long life, no explosion risk, suitable for power plant, substation and other power distribution system control or protection, especially suitable for opening and closing capacitor banks and important load and frequent operation occasions.
