Indoor Type Vacuum Circuit Breakers (also known as indoor vacuum breakers or vacuum interrupters) are electrical devices used to interrupt current flow in medium- and high-voltage systems. Designed for indoor use, they utilize a vacuum as the arc-quenching medium, ensuring safe and efficient power interruption. Commonly used in industrial facilities, substations, and power distribution networks, these breakers provide reliable overcurrent protection, durability, and low maintenance requirements.
