Eaton’s new NRX NF frame-fixed front connect breaker offers cable, compression lug, or bus-type circuit breaker connections, providing design flexibility in applications up to 1200A for the  UL 489 market.

Power management company Eaton (Pittsburgh, PA) has unveiled its front connect NRX NF fixed-frame air circuit breaker (ACB). Claiming the smallest breaker footprint in the ACB Underwriters Laboratory (UL) 489 market, Eaton says the NRX NF fixed-frame ACB helps to simplify installation, and reduce maintenance time and costs within facilities.

According to the company, the new breaker features front access to connections while allowing customers the ability to connect to the breaker with a busbar, cables, or compression lugs, providing design flexibility up to 1200 amperes (A). Additionally, the new unit's 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 is designed to reduce maintenance time and costs in engine generator, commercial and industrial distribution or emergency backup power and isolation applications.
