JCZ1-40.5kV Series Vacuum Contactor
This series of high-voltage vacuum contactors are made of high-quality vacuum switch tubes, with metal frames and insulating brackets, with excellent breaking performance, suitable for single-phase or two-phase power network systems below 40.5KV, for long-distance connection and breaking, frequency violet start and control resistive, inductive and capacitive loads and other occasions. JCZ1 series unipolar high-voltage vacuum contactor is often used in power protection occasions such as signal source arc suppression, detuning neutral point grounding, load box, etc., as a grounding main switch, with the advantages of small size, fast closing and separating speed, strong breaking capacity, etc., and can be used in 40.5k power system or 12k/power system above 4000 meters above sea level.
Choose high-quality vacuum switch tubes, with metal frames and insulating brackets.
It has excellent breaking performance.
It has the advantages of small size, fast closing and splitting speed, and strong breaking capacity.
