Feature → Business Impact → Application: The MPSC304VEAXXSW utilizes a four-pole Magnum PXR frame with fixed vertical mounting, delivering strong physical stability and straightforward installation in compact switchgear enclosures, reducing commissioning time on site. This translates to measurable uptime gains and lower labor costs during commissioning and maintenance, especially in high-density panels used in manufacturing lines. Feature → Business Impact → Application: The unit’s rated uninterrupted current of 3000 A and an interrupt rating of 100 kAIC ensure reliable fault current interruption for large feeders, minimizing arc energy and protecting downstream equipment in motor control centers and distribution panels. This is essential for industries with high short-circuit energy, such as metals processing and heavy manufacturing. Feature → Business Impact → Application: Although shipped without a trip unit, the Magnum PXR frame supports an upgrade path to Power Xpert Release trip units, enabling scalable protection strategies without replacing the breaker later, reducing total cost of ownership. Feature → Business Impact → Application: The product carries multiple certifications (UL Listed, ANSI, CE Marked, with additional industry tags in the data pack) that reassure procurement teams across regions, simplifying supplier qualification and helping maintain compliance. Feature → Business Impact → Application: Availability of renewal parts and detailed technical literature supports long-term lifecycle management, enabling proactive maintenance programs and reducing downtime risk in critical electrical rooms. Feature → Business Impact → Application: The 160 lb weight and 21.2 in width, 16.8 in height, and 14.6 in depth dimensions simplify space planning and enable more compact panel design without sacrificing protection, a common requirement in modern automation architectures.
