Product Description

Product Description

The electricity sector is rapidly changing, with major new trends such as energy efficiency, connectivity, and smart grids pouring into the arena and triggering new customer and application demands. To meet these needs, AB-B has now taken it a step further
Emax 2. Now, the Emax 2 air circuit breaker has become a versatile platform capable of managing next-generation electrical devices such as microgrids, evolving into a true energy manager. The Emax 2 is the first air circuit breaker to meet all the requirements of the new grid. It communicates directly with the AB-B Ability EAM cloud platform for energy efficiency optimization and asset health management.
  If the smart and plug-and-play architecture brings ease of use to Emax 2, cutting-edge connectivity capabilities give the circuit breaker the ability to evolve over its lifecycle. With the AB-B Ability MarketplaceTM, even installed devices can be upgraded. With unmatched electrical performance, the Emax 2 sets a new circuit breaker benchmark for current and future needs.
