Product Description
Vacuum circuit breakers are equipped with a modular spring-operated mechanism, which ensures high mechanical stability. They can be energized using either alternating or direct current power sources, and they also have the capability for manual energy storage. These breakers have several advantages, including compact size, strong breaking capacity, high insulation strength, pollution-free operation, and no risk of explosion. They are suitable for both fixed installation units and can be combined with a dedicated driving mechanism to form a trolley unit for use.
