With a 1200 A rating and 100 kA fault-current capacity, this Magnum breaker delivers fast fault clearance while protecting upstream equipment. The rating reduces arc energy exposure and minimizes downtime, making it ideal for main feeders in data centers, machine rooms, and high-demand manufacturing lines. The four-pole design and fixed vertical mounting provide balanced fault paths and secure installation in standard panels, improving disconnect reliability during high-current events and enabling straightforward retrofits for existing switchgear. The PXR20 LSI trip unit offers adjustable protection curves and remote configuration via Power Xpert Protection Manager, enabling precise selective coordination that lowers downstream tripping and simplifies maintenance planning. Global compliance and robust construction support easy procurement across regions, while the 160 lb frame and solid build deliver vibration resistance in harsh environments. The Magnum’s standard frame and compatibility with Magnum PXR streamline upgrades, spare parts logistics, and field service workflows, boosting deployment speed and reducing total cost of ownership. Access to Eaton’s application notes, manuals, and coordination papers further accelerates commissioning and ensures best-practice protection strategies for complex systems.
