Four-pole Magnum frame with PXR20 LSIGAM trip unit provides precise, coordinated protection for main feeders and motor control centers. Business impact: faster fault isolation and reduced arc energy translate into longer motor life, lower maintenance costs, and less unscheduled downtime. Application: ideal for large-process plants, packaged equipment, and distribution panels where high fault current and demanding loads require robust protection. This configuration also supports selective coordination strategies to minimize cascading trips. Feature: 4000 A continuous current rating with a 100 kA interrupting capacity delivers reliable circuit interruption for high-current faults. Business impact: enhanced system resilience, safer shutdowns, and compliance with demanding electrical codes. Application: service entrances, MCC sections, and heavy-duty feeders in chemical, oil, and metals processing where downtime is costly. Feature: Fixed horizontal mounting on a double standard frame plus dimensions tuned for large enclosures improves mechanical fit and eliminates excessive field fabrication. Business impact: reduces installation time, minimizes field wiring errors, and lowers total cost of ownership. Application: retrofit projects and new builds where alignment with existing buses and cable trays is critical. Feature: PXR20 LSIGAM trip unit enables selective coordination with time-current curves and is compatible with Power Xpert Protection Manager for centralized protection management. Business impact: clearer visibility into protection settings, faster responses to faults, and easier compliance reporting. Application: facilities pursuing advanced protection schemes, remote monitoring, and arc-flash mitigation across multiple zones. Feature: Broad certifications including UL Listed, CE Marked, NEMA Compliant, CSA, KEMA, and Lloyd's Register support global deployment. Business impact: accelerates procurement cycles, expands supplier base, and reduces regulatory risk while ensuring ongoing service and renewal parts availability. Application: multinational facilities, OEMs, and service providers requiring standardized protection across sites.
