Four-pole Magnum PXR standard-frame design with drawout vertical mounting and motorized racking enables safe, rapid maintenance and precise protection coordination in MCCs and panelboards, reducing downtime and service time. This translates to measurable uptime gains, easier changeovers, and smoother retrofits in complex distribution schemes. Rated uninterrupted current (Iu) of 3000 A and an interrupt rating of 100 kAIC provide headroom for high fault currents, improving system resilience and simplifying coordination studies for large facilities. The PXR25 LSIGAM ARMS trip unit delivers advanced protection curves and selective coordination, reducing nuisance trips while maintaining robust safety margins in high-demand environments. With multiple certifications and CE marking, the unit supports global deployment and regulatory compliance across diverse markets. The compact footprint (drawout, motorized racking, standard frame) and integration with Power Xpert Protection Manager streamline installation, commissioning, and ongoing protection monitoring for modern electrical infrastructures.

FAQs

The MPSC304MEAXX2S is designed for industrial power distribution, including motor control centers, distribution panels, and large switchgear. Its four-pole Magnum PXR design and 3000 A Iu rating support high-demand feeders, while the 100 kAIC interrupt capacity protects essential circuits from fault currents. This makes it ideal for manufacturing lines, data centers, and processing plants where reliability and selectivity are critical.
The PXR25 LSIGAM trip unit provides advanced protection logic with LRMS-style tripping characteristics and ARMS coordination to minimize nuisance trips while preserving safety. It enables precise long-time, short-time, and instantaneous protection settings, improving selectivity between upstream and downstream devices. This results in better fault isolation, reduced downtime, and easier compliance with protection standards in complex electrical networks.
Yes. With four-pole, standard-frame construction and motorized racking, the MPSC304MEAXX2S is optimized for MCCs and panel boards. The motorized racking simplifies maintenance and swapping of units, while the high current rating and 100 kAIC interrupt capacity support reliable motor protection and feeder safeguarding in demanding applications such as conveyors, pumps, and processing lines.
This breaker carries ANSI and UL listings, CSA, KEMA, ABS, and DNV GL certifications, along with CE marking and NEMA compliance. These qualifications support global product acceptance, ease audits, and help meet international electrical codes and standards for marketplaces in North America, Europe, and beyond.
Maintenance benefits include safer, faster servicing thanks to motorized racking and a drawout design, plus easier replacement and upgrade paths in protection architectures. ROI is driven by reduced downtime from improved protection coordination, lower risk of nuisance trips, and streamlined monitoring through Power Xpert Protection Manager integration, which enables proactive maintenance and faster fault diagnosis.
