Three-pole E-frame design aligns with Pow-R-Way III busway installations, delivering coordinated protection across all phases. This topology reduces the risk of uneven fault currents and simplifies panel layout, enabling engineers to consolidate protection modules without duplicating components. In manufacturing floors and distribution rooms, this design supports scalable protection for feeders and motors, while easing future capacity upgrades. 150A rated amperage with 65 kAIC interrupt rating at 240 VAC ensures robust fault handling for typical industrial loads. This translates to shorter fault clearing times and reduced damage to downstream equipment, cutting downtime and maintenance costs. In mixed-load environments with motor starts and inductive loads, you gain dependable protection without compromising system stability. 100% Neutral and 50% integral grounding options simplify grounding strategies and improve fault clarity. This feature helps meet sensitive electrical codes and reduces neutral-ground fault concerns in busway configurations. For critical systems such as programmable controllers or safety interlocks, reliable neutrals support predictable operations. Plug-in unit design enables rapid replacement, minimizing downtime during maintenance or upgrades. Jobsite technicians can swap the unit without rewiring entire panels, cutting mean time to repair (MTTR). In facilities with frequent reconfiguration, the plug-in approach supports modular expansion. Compliance and certification—NEMA, UL 857, CSA, and IEEE—provide regulatory confidence for safety-critical installations. This reduces procurement risk and accelerates project approvals, especially in regulated industries such as food & beverage, pharma, or water treatment. The combination of standards support helps facility managers meet audits and insurance requirements. Clear dimensional footprint and enclosure compatibility ease installation in existing cabinets, with a footprint of 12.36 in depth, 21.2 in height, and 5.43 in width and a 25 lb weight. The moderate size and weight support handling by standard tools and lift devices on site. This product fits a broad range of Eaton Pow-R-Way III configurations from 15 to 225 A, ensuring future-proofing for plant modernization.
