ABB Emax 2 circuit breaker helps panel builders downsize switchboards by 25%

Emax 2 circuit breaker delivers space and cost savings with its unique compact design

Hanover, April 13, 2015 – ABB, the leading power and automation technology group, thanks to Emax 2 circuit breaker technology is driving a new era of switchboard optimization, by enabling panel builders to reduce switchboard sizes and material costs by up to 25%.

ABB Emax 2 is the first low-voltage air circuit breaker (ACB) that offers the maximum performance in the most compact frame dimension. To meet customer’s demands, ABB Emax 2 comes in four different sizes with a mechanical design that reduces the cubicle installation. In addition, thanks to the smart electronics on board, Emax 2 is enabling panel builders to remove components from the switchgear as well as external devices and sensors.

Global Head of ABB’s Breakers and Switches business, Giampiero Frisio said: “ABB’s Emax 2 is the first circuit breaker that can deliver cost savings in footprint, volume and copper of up to 25%. Panel builders are using Emax 2 to make their switchgears smaller, more intelligent and more cost-effective. In many sectors, including marine and critical power, switchboard downsizing adds significant value in order to reach the customer’s needs’’.

Emax 2 represents ABB’s vision of a more sustainable and efficient future.  Replacing traditional breakers with ABB Emax 2 would reduce the amount of copper consumed in switchgear production by 8.8 million kilograms, enough to electrify a new 6,600km railway stretching from Italy to China. The other metals parts saved altogether each year would weigh 14 million kilograms – the same as New York’s Brooklyn Bridge. These savings also result in fewer trucks on the road and an approximate reduction of 7 tonnes of CO2 per year – 2,000 football pitches would need to be planted with 400,000 trees to produce a similar environmental benefit.

ABB’s Global Product Manager for air circuit breakers, Giuseppe Scali, said: “Panel builders no longer want standard circuit breakers that waste space and expensive materials. Emax 2 is the benchmark circuit breaker because it gives them the opportunity to produce smaller, more powerful switchboards that deliver more value than the traditional solution – they can see the savings using ABB’s straightforward online calculator.

ABB Emax 2 is a groundbreaking evolution of a circuit breaker into a Power Manager, introducing a greener, better world.

This innovation is in line with ABB's Breakers & Switches business’ commitment for innovation which supports efficient energy consumption and improved productivity for its global customer base.
