FAQs

The MPSC324WEAXX2H uses a standard Magnum four-pole, drawout vertical mounting designed for common low-voltage switchgear footprints. This enables straightforward retrofits into existing cabinets with minimal cabinet clearance changes. Verify the connector and interlock compatibility, and plan for any required accessory kits to maintain proper mechanical and electrical alignment during replacement.
The PXR20 LSIAM trip unit offers advanced protection functions, local and remote signaling, and integration with Power Xpert Protection Manager. This enables accurate coordination with upstream devices, targeted fault isolation, and easier tuning of protective curves for diverse motor loads, improving uptime and reducing nuisance trips in dynamic production environments.
This breaker is UL Listed and CE Marked, with additional certifications including ANSI, CSA, KEMA, Lloyd's Register, DNV GL, and ABS in various regions. NEMA compliance and SABA listing are noted in the datasheets, supporting safe operation in multinational facilities and simplifying cross-border procurement.
Plan for a drawout replacement to minimize downtime, verify mechanical interlocks and trip unit compatibility, and update protection settings to match system coordination. Use the Magnum PXR product aids and manuals for correct configuration. Ensure remote monitoring wiring if Power Xpert Release is deployed and schedule routine inspections of contacts, springs, and insulation integrity.
Expected ROI stems from reduced downtime due to precise tripping, improved selectivity, and easier maintenance with field-tuneable protections. The ability to upgrade within the Magnum PXR family reduces lifecycle replacement costs, while remote monitoring capabilities enable predictive maintenance, lowering overall total cost of ownership in busy industrial facilities.
