JCZ1-6kv(7.2kv)/10kv(12kv) High Voltage Vacuum Contactor
This series of medium-voltage vacuum contactors uses high-quality vacuum interrupters, combined with a metal frame and insulating supports, providing excellent breaking performance. They are suitable for single-phase or two-phase power network systems below 6KV(7.2KV) and 10KV(12KV), allowing for long-distance switching and interruption, frequent starts, and control of resistive, inductive, and capacitive loads. The JCZ1 series single-pole medium-voltage vacuum contactor is commonly used in power protection applications such as signal source arc suppression, harmonic neutral grounding, and load boxes. As a main switch, it features a compact size, fast making and breaking speeds, and strong interruption capacity.
