Drawout vertical design with motorized racking reduces maintenance downtime and minimizes arc‑flash exposure during breaker replacements. In practice, technicians rack breakers safely from a distance, accelerating changeouts in tight spaces and preserving production uptime in manufacturing lines. The PXR25 LSIGAM electronic trip unit provides long‑time, short‑time, and instantaneous protection with adjustable curves and settings for selective coordination. This enables precise protection across feeders and motors, reducing nuisance trips and improving plant reliability during heavy startup currents. With a 6000 A frame and 85 kA short‑circuit rating, the Magnum can handle high fault currents typical in process plants and large motors, keeping downstream equipment safer and enabling safer startup and maintenance windows. Compatibility with Power Xpert Protection Manager and Magnum PXR ecosystem enables centralized protection management, faster configuration, and easier troubleshooting, supporting digital modernization initiatives and remote monitoring for maintenance planning. UL Listed, CE Marked, CSA Certified alongside SABA and CCC marks ensure global acceptance and regulatory compliance, minimizing qualification gaps in mixed installations. Finally, the standard enclosure footprint and mechanical dimensions (16.3 in depth, 16.8 in height, 31.1 in width) plus a 237 lb weight provide a stable, install‑friendly platform that streamlines wiring, testing, and commissioning in existing switchgear.
