The standard for power circuit breakers around the world

Fuji DW Series ACB is the standard for power circuit breakers around the world. Over the years, other major manufacturers have tried to keep up by developing products incorporating DW’s most innovative features, including the breaking principle, modular design and the use of composite materials.
In addition to the traditional features of power circuit breakers (withdrawability, discrimination and low maintenance), DW ranges offer built-in communications and metering functions, all in optimised frame sizes.
DW incorporates the latest technology to enhance both performance and safety. It is easy to install, with user-friendly, intuitive operation and environment-friendly designs. DW is compliant with international standards IEC 60947-1 and 2, IEC 68230 for type 2 tropicalisation
It comes in 2 performance levels H1 - for industrial sites with high short-circuit levels or installations with two parallel-connected transformers and H2 - high-performance for heavy industry where very high short-circuits can occur
The DW series is available in two frame sizes, one from 800 to 4000 A and the other from 4000 A to 6300 A. DW can be integrated in a general supervision system to optimise your electrical installations. All DW series circuit breakers are equipped with an electronic control unit that offers a complete set of protections and state of the art measurements
