Rated Iu of 800 A and an interrupt rating of 100 kAIC provide robust protection for high-load feeders, supporting reliable power delivery in demanding environments. This translates to fewer nuisance trips and faster fault clearance, minimizing unplanned downtime and safeguarding critical equipment. The three-pole standard-frame design with drawout vertical mounting simplifies retrofits and field servicing, reducing installation cost and time while enhancing maintenance flexibility. The PXR20 LSIG trip unit enables selective coordination across feeder groups, improving protection accuracy and limiting fault impact to the smallest possible area. This capability not only strengthens safety and compliance but also reduces downstream energy waste and wear on downstream devices. Certifications and compliance—CE, UL, CSA—ensure global procurement confidence and streamlined audits, while compatibility with Power Xpert Protection Manager supports real-time monitoring and fault analytics for proactive maintenance. Overall, Magnum PXR offers durable protection with measurable reliability gains and a clear path to lifecycle cost savings in modern industrial power systems.
