JCZ1-7.2/12 High Voltage 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 7.2KV and 12KV, for long-distance connection and breaking, frequent start and control of 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., and is used as a grounding main switch, which has the advantages of small size, fast closing speed and strong breaking capacity.
Choose high-quality vacuum switch tubes, with metal frames and insulating brackets.
