FAQs

Installations begin with confirming panel and busbar compatibility for a three-pole drawout device. Mount the breaker in the drawout rack, connect control and power terminals per the Magnum installation guide, and enable motorized racking for controlled insertion and withdrawal. Verify clearances, torque settings, and trip unit configuration for the PXR20 LSIAM, then perform a factory-referenced commissioning test to confirm correct protection and selectivity.
Key specs include an 800 A current rating and a 100 kA short-circuit withstand, three-pole construction, standard frame, and the PXR20 LSIAM trip unit. These enable enhanced protection coordination with fast, selective tripping for high-current faults, reducing nuisance trips and improving system reliability in feeders, MCCs, and critical loads.
Yes. The MPSC083MEAXX2H is designed for heavy-duty power distribution with robust trip coordination and a motorized racking option that minimizes maintenance downtime. Its 800 A rating and 100 kA interrupt capability fit MCC requirements, while UL/Ce/CSA certifications help satisfy industry-specific safety and regulatory standards.
This breaker carries UL Listed, CE Marked, CSA Certified, and additional certifications from bodies like KEMA, Lloyd's Register, ANSI, ABS, and DNV GL. These certifications support regulatory compliance across regions, facilitate supplier qualification during audits, and ensure the equipment meets recognized safety and performance benchmarks.
ROI benefits arise from reduced maintenance downtimes due to rapid racking, improved protection selectivity lowering outage duration, and extended asset life from precise fault isolation. Combined with regulatory compliance and faster commissioning, the Magnum PXR configuration lowers total cost of ownership in ongoing operations and project deployments.
