The original Masterpact has set a new standard for power circuit breakers around the world. Over the years, other major manufacturers have tried to keep up by developing products incorporating Masterpact’s most innovative features. These include the breaking principle, modular design and the use of composite materials.

Today, Schneider Electric continues to innovate with the new Merlin Gerin Masterpact NW.
In addition to the traditional features of power circuit breakers (withdrawability, discrimination and low maintenance), Masterpact now offers built-in communications and metering functions, all in optimised frame sizes.
Masterpact NW incorporates the latest technology to enhance both performance and safety. Masterpact is easy to install with user-friendly intuitive operation and environment-friendly design; it is quite simply, the ultimate ACB.
