JCZ1-24kV Vacuum Contactor | Reliable High Voltage Control

JCZ1-24kV 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 24KV, 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 and opening speed, strong breaking capacity, etc., and can be used in 24kv power system or 12kv power system at an altitude of more than 4000 meters.
