PITTSBURGH, PA — Power management company Eaton today announced the new front connect NRX NF fixed-frame air circuit breaker (ACB), which helps simplify installation, and reduce maintenance time and costs. 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 (A). Additionally, advanced communications modules and trip units improve safety and control.

With easily accessible connections with replaceable parts, plug-and-play accessories and field-upgradable trip units, the NRX NF front connect fixed ACB reduces maintenance time and costs in engine generator, commercial and industrial distribution or emergency backup power and isolation applications.
