April 2, 2015 – A new front connect NRX NF fixed-frame air circuit breaker (ACB) has been unveiled from Eaton.

With the “smallest breaker footprint in the ACB Underwriters Laboratory (UL) 489 market,” the new breaker features front access to connections while allowing customers the ability to connect to the breaker with busbar or cables, providing design flexibility up to 1200 amperes, said Eaton. Additionally, “advanced communications modules” and trip units improve safety and control.
 
With accessible connections with replaceable parts, plug-and-play accessories and field-upgradable trip units, Eaton said the NRX ACB reduces maintenance time and costs in engine generator, commercial and industrial distribution or emergency backup power and isolation applications.

The NRX Digitrip 520M and 1150 electronic trip units offer Eaton’s patented Arc Reduction Maintenance System (ARMS) capabilities, giving customers “instantaneous protection,” the company added. The NRX NF fixed-frame air circuit breaker with the 1150 trip unit communicates with the Power Xpert Protection Manager PC tool, helping simplify customer trip unit setup and configuration.
 
“As demand for power increases, customers need accurate, reliable and safe protection for electrical systems and personnel, without sacrificing efficiency or uptime,” said Jeremy Schmidt, LVCB product manager with Eaton’s Americas branch. “Eaton is committed to developing electrical solutions to help meet these evolving needs, and the NRX NF front connect fixed ACB offers improved safety, control and flexibility.”
