Product Q&A

Q:What is the arc extinguishing medium of this vacuum interrupter?

Its arc extinguishing medium is ultra-high vacuum inside the fully sealed ceramic cavity. No toxic gas, oil or other media is needed. It quenches electric arcs instantly at current zero crossing, with eco-friendly and maintenance-free advantages.

Q:What installation method does this vacuum interrupter adopt? Is it compatible with ZN series circuit breakers?

It uses vertical bolt fixed installation. Standard threaded mounting holes are reserved on both upper and lower metal end caps. The size and mounting structure are universally matched with most ZN medium-voltage vacuum circuit breakers for easy assembly and replacement.

Q:How about the service life and operating speed of the product?

Optimized average closing speed effectively reduces contact bounce and contact wear, while sufficient average opening speed guarantees fast arc extinction. The hermetic ceramic-metal welding structure keeps stable vacuum permanently, supporting thousands of opening-closing cycles with long electrical service life.
