FAQs

The MPSC084WEAXXSW uses a standard Magnum four-pole frame with drawout vertical mounting, designed for easy drop-in replacement in compatible LV panels. It supports hot-swapping, simplifies panel layout, and integrates with existing bus and accessory hardware found in typical industrial switchgear. If your current installation is a standard frame Magnum lineup, upgrading or retrofitting with this model minimizes alignment issues and reduces commissioning time.
This unit is rated for 800 A with a 100 kA short-circuit withstand. It is a four-pole low-voltage breaker that ships without a trip unit, making it a stable platform for later trip-unit upgrades, including the Power Xpert Release (PXR). These ratings support robust protection for main and feeder circuits in demanding industrial environments and help ensure selective coordination when paired with appropriate trip units.
Yes, selective coordination is supported when paired with compatible trip units and coordination studies. Eaton provides application papers (such as selective coordination and zone selective interlocking references) and time/current curve data for Magnum PXR to assist engineers in designing properly coordinated protection schemes. For upgrades, consult the Magnum renewal parts and TD013013EN documentation to ensure ongoing compatibility.
The product carries UL Listed, ANSI, CSA certifications and CE marking, with KEMA certification noted, supporting global deployment. Additional approvals such as Lloyd's Register, ABS, DNV GL, and other certification marks may apply to related components or renewal parts. When auditing cross-border installations, these certifications simplify supplier qualification and regulatory compliance across multiple regions.
Maintenance benefits come from a drawout design that enables quick replacements and reduced downtime, and from availability of renewal parts and accessories for long-term lifecycle support. ROI improves through lower maintenance labor time, extended mean time between failures (MTBF), and easier sourcing via globally recognized certifications. Additionally, compatibility with Power Xpert Protection Manager enhances monitoring and modernization opportunities.
