The 5000 A Iu capacity and an 85 kAIC interrupt rating deliver robust overcurrent protection for high-inrush applications, reducing unplanned outages and ensuring safer fault clearing for motor feeders and critical distribution trunks in manufacturing lines. Drawout vertical mounting with motorized racking speeds maintenance, minimizes live-exposure during replacement and supports safe servicing in panel boards and switchgear housings. The PXR20 LSIGAM trip unit provides LSIG protection and ARMS coordination, enabling selective tripping and arc-flash mitigation across downstream devices with easy configuration through the Magnum PXr ecosystem. A double standard frame and three-pole Magnum PXR design standardize installations, improving procurement efficiency and spare-parts availability across projects. Global certifications—UL Listed, CE Marked, ANSI/CSA, KEMA, Lloyd’s Register, DNV GL—support multinational deployments and compliance documentation, while compatibility with Power Xpert Protection Manager enhances monitoring and fault analysis for operators seeking real-time insight.
