High-capacity protection with 6000 A Iu and 85 kAIC interrupt rating translates to fewer upstream faults and reduced nuisance trips in large MCCs and distribution panels. The three-pole Magnum PXR design, combined with a double standard frame and drawout vertical mounting with extensions, supports flexible installation in both new builds and retrofits across heavy industrial environments. The Magnum PXR trip unit with LSIAM arms enables improved selective coordination, enabling zone selective interlocking where applicable. This reduces the scope of fault energy and limits outages to the minimum zone, improving uptime in critical processes such as packaging lines or metal fabrication. Installation and maintenance are streamlined by the drawout design and extensions mounting, allowing vertical installation with straightforward removal and testing. Compatibility with Power Xpert Protection Manager provides remote monitoring, event logging, and fleet protection analytics, which helps maintenance teams plan replacements and optimize lifecycle costs. The unit’s rugged construction fits standard industrial enclosures, supports zone selective interlocking, and enhances selective protection. UL Listed, CSA Certified, CE Marked, and NEMA compliant, it meets global regulatory requirements for multi-site deployments. These features deliver faster fault isolation and measurable uptime gains in critical processes.
