ABB Nigeria introduced its state of the art Emax 2 LV air circuit breaker to the Nigerian Market. Emax 2 is the first low-voltage air circuit breaker with integrated energy management functions that can potentially save 5.8 million megawatt-hours (MWh) annually when compared to traditional breakers.
The SACE Emax 2 air circuit breaker can save energy by using loads more efficiently and also flatten load demand to reduce demand charges. Breakers like the Emax 2 are widely used in low-voltage environments in various industries and applications including commercial buildings, manufacturing plants, data centers and ships.
The breaker is with smaller dimensions comparing to its predecessor, and is equipped with a communications chip that runs on the IEC standard and is embedded with ABB’s power controller technology that uses software to manage nonessential downstream loads. The system can work with any building management system or can operate on its own.
The breaker contains a protection trip relay with an integrated power controller that measures and evaluates energy consumption, then manages the loads to maintain or reduce the peak power usage as determined by the user. This will also help prevent blackouts since the root cause is often peak demand exceeding supply.
ABB expects that customers could use the circuit breakers not just to save money by shifting load, or reducing the width of the switchboards and the related copper busbar, but also maybe to make some money off of demand response programs.
“With Emax 2, ABB has created the perfect blend of control, connectivity, performance, ease of use and safety that not only meets today’s needs, but anticipates the needs of tomorrow. So let’s enjoy managing the power” Said Ahmed Gamal, The low voltage Division Manager for ABB Nigeria
The development of the new Emax 2 breaker was led by ABB’s development center in Bergamo, Italy
As one of the world’s leading engineering companies, ABB help our customers to use electrical power efficiently, to increase industrial productivity and to lower environmental impact in a sustainable way. ABB is investing $1.5 billion annually in R&D activities running by 8,000 scientists and engineers with collaboration with 70 universities all over the world.
