TD-1.14 series. The rated voltages of these vacuum interrupters are less than 1140 volts, and can be used in low-voltage scenarios. Particularly worth mentioning is that TD-1.14 adopts special material for contacts and transverse magnetic field electrode structure, so that the rated current reached 1600A ~ 6300A，and range of short-circuit breaking capacity covers 65kA ~ 120kA. At the same time, TD-1.14 adopts special shielding cover and elongated ceramic insulating shell to ensure that the insulation capacity of the vacuum interrupter will not decrease even after 30 times of short-circuit breaking, and adopts high-performance Ω-shaped bellows made of special materials, enables the mechanical endurance of the interrupter to reach 30,000 times, which is suitable for frequent operations.
