Feature → Business Impact → Application: The PXR20 LSIAM trip unit enables precise, adjustable protection logic that improves selective coordination across feeders, reducing the scope of outages and arc energy exposure in critical loads. This translates to higher system availability and safer commissioning in automation and processing lines. Application: motor control centers, large distribution panels, and process plants where downtime is costly and safety standards are strict. The 1600 A rating and 100 kA short-circuit capability deliver resilience for demanding equipment like pumps, compressors, and drives, minimizing the risk of cascading faults and enabling faster restoration after faults. The three-pole drawout vertical mounting simplifies installation, maintenance, and future uprates, reducing panel downtime during replacements and upgrades. Compatibility with Power Xpert Release trip units enhances integration with protection management systems, supporting centralized monitoring and diagnostics. The unit ships with broad compliance (UL, CE, NEMA) to streamline audits and cross-border deployments, lowering project risk and accelerating commissioning. Arc-energy reduction techniques improve operator safety and help meet evolving factory safety programs, translating to lower insurance and compliance costs. In practice, engineers gain a proven path to scalable protection with consistent performance in new builds and retrofits alike.

FAQs

This model uses a three-pole drawout vertical mounting design, enabling straightforward insertion/removal without panel disassembly. Ensure compatible bus, mount rails, and clearance for the 14.6 in depth and 16.8 in height. Use proper latching and alignment to maintain optical trip-unit access and safe arc-flash clearances.
The PXR20 LSIAM trip unit provides advanced electronic protection that enables precise coordination between upstream and downstream devices. This reduces the impact of a fault to the nearest protected section, shortens restoration time, and minimizes arc energy exposure, which is critical for uptime in manufacturing and process facilities.
Yes. The MPSC163WEAXX2H carries UL Listed and CE Marked approvals, plus additional certifications (ANSI, CSA, ABS, DNV GL, KEMA, Lloyd’s Register, and more). This broad certification portfolio supports worldwide compliance programs, simplifying bids and audits for multinational projects.
Ideal for motor control centers, large distribution panels, and industrial automation racks in sectors like oil and gas, mining, metals, and water treatment. Its 1600 A/100 kA rating and selective-coordination capabilities help protect high-capacity feeders while maintaining service continuity in critical loads.
Magnum PxR enables modular diagnostics, easier replacement of trip units, and easier retrofits, reducing maintenance downtime. The combination of robust protection and energy management supports longer service intervals, lower repair costs, and reduced downtime, delivering clear ROI in facilities with high uptime requirements.
