Feature → Business Impact → Application: The Magnum low voltage power circuit breaker uses a PXR20 LSIG trip unit to deliver precise protection curves, enabling selective coordination that minimizes unneeded outages while safeguarding critical loads in panelboards and switchgear. This translates to higher system uptime and lower repair costs in industrial power distribution. Application: Ideal for panels serving motors, conveyors, and process lines where accurate fault clearance is essential. Feature → Business Impact → Application: Drawout vertical mounting simplifies replacement and maintenance, reducing maintenance window times and enabling faster project commissioning in retrofit and new-install scenarios. Application: Suitable for modular data centers and OEM-built switchgear where quick swap-out is valuable. Feature → Business Impact → Application: Robust interrupt capacity of 85 kA and current rating up to 5000 A (ABCABC) provide resilience against high fault currents, protecting equipment and reducing collateral damage in heavy-duty manufacturing lines. Application: Critical for machine floors and heavy machinery where fault currents are common. Feature → Business Impact → Application: Double standard frame and three-pole configuration deliver predictable trip behavior and ease of coordination across feeders, supporting safer system-wide protection schemes. Application: Power distribution panels with multi-branch circuits. Feature → Business Impact → Application: Comprehensive certifications (UL Listed, CSA Certified, CE Marked) streamline global deployment and supplier qualification, reducing procurement hurdles. Application: Global plants and projects requiring strict regulatory compliance. Feature → Business Impact → Application: Compatibility with Power Xpert Protection Manager enables centralized protection management and monitoring, improving asset visibility and maintenance planning. Application: Industrial automation environments using protection management software for proactive outages and analytics.

FAQs

When installing the MPS8503WEAXX2C, plan for a drawout vertical mounting arrangement to simplify replacement and maintenance. Ensure panel space accommodates its 16.3 in depth x 16.8 in height x 31.1 in width footprint and confirm compatibility with three-pole, double-frame configurations. Verify clearance and wiring access per applicable codes to optimize protection performance and reduce install time.
The PXR20 LSIG trip unit provides adjustable protective settings with Least Significant Integral Gain logic, enabling precise overcurrent and short-circuit protection. This supports selective coordination across feeders, minimizes unnecessary trips, and improves reliability in motor and process circuits. For field use, LSIG’s algorithms help reduce nuisance trips while maintaining fast fault clearance.
Yes. With a 5000 A ABCABC interrupt rating and the PXR20 LSIG trip unit, this Magnum breaker is designed for selective coordination in multi-circuit power distribution. Properly tuned, it can coordinate with upstream devices to isolate faults with minimal impact on non-faulted loads, enhancing uptime in manufacturing lines and critical processes.
The product carries UL Listed, CSA Certified, and CE Marked certifications, along with additional approvals (KEMA, Lloyd’s Register, ANSI, DNV GL, ABS). This broad certification portfolio supports regulatory compliance for global deployments, supplier qualification, and risk mitigation in cross-border industrial installations.
Maintenance focuses on periodic inspection of drawout contacts, trip unit calibration, and module replacement as part of protection manager workflows. ROI is driven by reduced downtime from selective coordination, faster field replacement due to vertical drawout mounting, and extended device life from robust interrupt ratings. Leveraging Power Xpert tools can further optimize maintenance planning and asset performance.
