4 W-VACi Series Vacuum Circuit Breakers by Eaton electric sector is an encapsulated insulation indoor Medium Voltage Vacuum Circuit Breakers. Products fully comply with the requirements of National standard GB198 (Equivalent to IEC ), Industry standard DL/T03, and has been the first option for control and protection of medium voltage transmission system and Power distribution system. Eaton leading Power distribution industry Eaton has over 80years manufacture experience of Circuit Breakers. Over the past 80years, we are leading global circuit breaker market with the most advanced technology and concept. In the World advocating environment conservation, the expectation for medium voltage power switching is very high. Along with lower impedance system configuration, the demand for current continuity and breaking capacity is higher, meanwhile the demand for installation in limted spaces and cooling is more stringent. The optimal solution is our medium voltage Circuit Breakers with advantages of pro-environment, reliably breaking heavy-duty current, without extra cooling or forced air cooling. EATON has integrated over 100 years, vacuum technology, and rich application experience of Westinghouse, Cutler-Hammer and Holec. In 1920s, EATON began the R & D of vacuum interrupter, in 1960s commercialized Vacuum Circuit Breakers. EATON has 70 years design and manufacture experience for Circuit Breakers and switchgear.
