Four-pole protection with the PXR20 LSIG trip unit enables selective coordination and precise overload detection. This reduces nuisance trips and shortens fault-clearing times, protecting transformers and motors alike. It’s ideal for large motor feeders in manufacturing lines and process automation panels. Drawout vertical mounting simplifies installation and field maintenance, allowing breakers to be swapped with minimal panel downtime. The design supports faster maintenance cycles, reducing labor costs during commissioning or upgrades in automation plants. 6000 A frame rating with 85 kA short-circuit capability provides robust protection for high-energy systems, facilitating safe integration with feeders, starters, and bus systems in heavy industry. Fan-cooled construction maintains performance in dense cabinets, and LSIG diagnostics provide visibility into system health for timely replacements. UL Listed, CE Marked, and NEMA compliant certifications support global deployment while enabling integration with Power Xpert Protection Manager for advanced monitoring and maintenance planning. Overall, the Magnum MPS86A4WEAXX2C reduces downtime, improves reliability, and lowers lifecycle costs by simplifying maintenance and improving fault isolation.

FAQs

What to verify before installation includes ensuring proper de-energization, verifying clearance for the drawout mechanism, and confirming vertical mounting compatibility with the existing panel. Use correct wiring for the PXR20 LSIG trip unit and follow Eaton's installation guidance to minimize commissioning time and prevent mis-wiring that could affect coordination and protection.
Key performance specs include a 6000 A frame rating and an 85 kA short‑circuit capability, four-pole construction, and the PXR20 LSIG trip unit. These features deliver precise overload protection, fast fault clearing, and robust safety margins for high-energy industrial feeders in demanding environments.
Yes. The PXR20 LSIG trip unit supports selective coordination with a four-pole design, enabling precise fault isolation and minimizing the impact of faults on upstream equipment. For motor control centers, this enhances reliability and safety while reducing unnecessary outages during startup and fault events.
This model carries UL Listed, CE Marked, and NEMA compliance, along with CCC marking and several third‑party certifications (CSA, Lloyd's Register, ANSI, KEMA, ABS, DNV GL). These certifications support global deployment, regulatory adherence, and safer operation across diverse regional markets.
ROI benefits come from reduced downtime due to improved selective coordination and quicker fault isolation, easier maintenance with drawout mounting, and enhanced monitoring through Power Xpert Protection Manager. The result is higher equipment availability, lower maintenance labor costs, and longer lifecycle protection for critical manufacturing assets.
