High current rating and robust interrupt capability deliver fast fault clearing for feeders, protecting downstream equipment and minimizing arc energy. This translates to shorter outages and lower repair costs in demanding applications such as data centers, heavy manufacturing, and large motor drives. The 2000 A Iu and 100 kAIC rating enable reliable performance under peak loads and fault conditions. The PXR25 LSIGAM trip unit provides selective coordination, so only the faulted section trips, preserving uptime for non-affected circuits in process plants and mission-critical facilities. Four-pole configuration with a standard frame and fixed horizontal mounting simplifies field installation, reduces wiring complexity, and improves rack compatibility in switchgear. The broad certifications—UL Listed, ANSI, KEMA, LR, CSA, CE, NEMA, CCC—facilitate global procurement and regulatory approvals, while extensive technical resources and Power Xpert Protection Manager compatibility accelerate commissioning and ongoing maintenance.

FAQs

The MPSC204HEAXX2S is designed for fixed horizontal mounting in standard switchgear frames. With a four-pole configuration and a standard frame, it drops into common LV panels without adapters. Dimensions and mounting alignment (14.6 in depth, 16.8 in height, 21.2 in width) support straightforward field installation, minimizing commissioning time and reducing the need for custom hardware.
Key specs include a 2000 A Iu rating and a 100 kAIC interrupt rating, four poles, and the PXR25 LSIGAM trip unit. This combination enables high-capacity protection with selective coordination, ensuring fast fault clearance while limiting outages to affected sections. The unit is suitable for large feeders, motor drives, and critical processes in industrial environments.
Yes. The Magnum PXR family integrates with Eaton's Power Xpert Protection Manager, enabling centralized monitoring, event reporting, and coordinated protection across multiple devices. This compatibility supports faster commissioning, proactive maintenance, and improved visibility into protection schemes for engineers managing complex LV installations.
The MPSC204HEAXX2S carries UL Listed and ANSI certifications, plus KEMA, Lloyd's Register, CSA, DNV GL, and ABS attestations, along with CE marking and other compliance marks such as NEMA and CCC. This broad certification portfolio reduces procurement risk and eases cross-border approvals for global projects.
Maintenance is typically driven by routine inspection of protection schemes and routine verification of trip unit settings. The PXR25 LSIGAM unit’s reliable coordination reduces nuisance trips, lowering maintenance interruptions. A well-implemented Magnum PXR protection strategy can shorten downtime, extend asset life, and improve overall ROI by stabilizing production uptime and reducing unplanned outages.
