Feature → Business Impact → Application: The three-pole F-frame Pow-R-Way III design enables robust protection in compact footprints, reducing space requirements while delivering dependable overcurrent protection for motor control and distribution in busy panels. This design translates to lower maintenance downtime and faster part replacement in high-demand facilities, particularly within busway solutions used in manufacturing floors. Application: ideal for three-phase bus duct layouts where quick plug-in breakers streamline service and upgrades. Feature → Business Impact → Application: Amperage rating of 125A paired with a 40 kAIC interrupt rating at 220–240 VAC provides strong fault current handling, improving system safety margins and protecting sensitive equipment from surges. This supports critical processes with high inrush currents in packaging, metalworking, and continuous process industries. Application: suitable for main feeder protection in industrial power distribution schemes. Feature → Business Impact → Application: 100% Neutral and 50% Internal Ground grounding options ensure reliable fault clearance paths and stable system reference, reducing nuisance trips and improving control reliability for drive systems and programmable logic controllers. Application: supports precise neutral grounding in busway circuits and versatile protection schemes. Feature → Business Impact → Application: NEMA compliance along with CSA, IEEE, ANSI, and UL 857 certifications delivers regulatory alignment and cross-border compatibility, minimizing procurement risk and accelerating approval cycles. Application: ideal for multinational plants and equipment installations requiring robust certification portfolios. Feature → Business Impact → Application: Integrated plug-in unit design simplifies installation and future maintenance, enabling quick upgrades without extensive wiring work. This reduces total installed cost (TIC) and downtime during routine maintenance or expansion. Application: compatible with Eaton Pow-R-Way III busway systems and modular power architectures in modern facilities.
