DESCRIBE

The ABB ConVac series are medium‑voltage vacuum contactors engineered for switching and control of electrical loads in medium‑voltage systems. These contactors use vacuum interrupter technology to provide reliable making, carrying, and breaking of normal operating currents for motors, transformers, capacitor banks, and other heavy loads. ConVac vacuum contactors are designed to support frequent switching operations, operate in harsh environments, and integrate easily into electrical equipment such as motor control centers, switchgear, and capacitor switching panels
