Feature → Business Impact → Application: The MPSC304VEAXX2A delivers a high current rating of 3000 A with a 100 kA short-circuit withstand in a four-pole Magnum frame. This combination minimizes the risk of nuisance trips and protects expensive drives and feeders under fault conditions. Ideal for large motor feeders, press lines, and distribution panels in heavy industry where uptime matters. Feature → Business Impact → Application: Equipped with the Power Xpert Release (PXR) LSI trip unit, the breaker delivers precise, selective protection and reduced arc energy. The protection manager compatibility enables centralized settings and easier compliance documentation. Use this in facilities requiring coordinated protection for multiple feeders, such as extrusion lines or paper mills, to improve reliability while simplifying commissioning. Feature → Business Impact → Application: Fixed vertical mounting on a standard Magnum frame simplifies retrofits and new installs, with dimensions that fit common enclosures. The four-pole construction supports synchronized switching across phases, ensuring balanced protection. This makes it a straightforward upgrade for legacy systems and modern installations in plant automation, data centers, and process industries where space optimization matters. Feature → Business Impact → Application: Broad, multi-region certifications—UL Listed, ANSI, CE, KEMA, and others—support global deployment and reduce third-party validation time. Compliance confidence translates to faster approvals, fewer site delays, and a lower total cost of ownership for projects spanning North America, Europe, and Asia. This is particularly valuable in regulated industries and multinational facility rollouts. Feature → Business Impact → Application: A rich portfolio of resources, including application notes on zone selective interlocking, renewal parts, and manuals, backs lifecycle maintenance and continuous improvement. Access to Zone Selective Interlocking papers and product aids accelerates troubleshooting and reduces downtime in field service. This knowledge base helps maintenance teams plan proactive replacements, achieving better uptime and asset utilization.
