Quick Summary

The Eaton Magnum low voltage power circuit breaker protects electrical distributions in industrial panels by safely interrupting fault currents. Engineers often contend with nuisance trips, limited interrupt ratings, and maintenance complexity, which this unit mitigates through a robust trip system and modular design. Certifications including UL Listed, CE Marked, and CSA Certified provide cross-market compliance, while the PXR20 LSIG trip unit enables precise protection. This combination translates to reduced downtime, easier spare parts planning, and stable arc energy management for production lines.

Feature → The device delivers a 4000 A rated uninterrupted current (Iu) and a 100 kAIC interrupt rating across a three-pole, drawout configuration with a Magnum PXR trip unit. Business Impact → High fault-energy apps stay protected with fast, reliable interruptions, reducing unplanned downtime and improving protection coordination across feeders. Application → Ideal for data centers, large manufacturing lines, and complex LV distributions where energy reliability is critical. Feature → Magnum PXR trip unit with LSIG (low-energy, high-precision) logic. Business Impact → Improves selective coordination and minimizes arc flash energy during faults, supporting safer operations and lower maintenance costs. Application → Suitable for motor feeders and MCCs requiring precise protection settings. Feature → Double standard frame and three-pole, drawout vertical mounting. Business Impact → Simplifies retrofits and serviceability, reducing commissioning time and spare parts inventory. Application → Fits standard panel buses and existing mounting rails in retrofit projects. Feature → Comprehensive certifications (UL Listed, CE Marked, CSA Certified, etc.). Business Impact → Global acceptance reduces procurement friction and unscheduled site rollouts. Application → Multinational plants and distributors needing consistent compliance. Feature → Compatibility with Power Xpert Protection Manager (PXPM) and available documentation. Business Impact → Enables remote monitoring, event logging, and easier protection management, supporting predictive maintenance. Application → Data-driven maintenance programs and centralized protection management. Feature → Zone selective interlocking (ZSI) and coordination resources in Eaton literature. Business Impact → Enhances fault isolation and reduces system-wide disruption in complex panel assemblies. Application → Critical in coordinated protection schemes for large switchgear and distribution networks.

FAQs

Yes. The MPSC4N3WEAXX2C uses the Magnum PXR trip unit with a compatible double standard frame, three-pole drawout construction, and vertical mounting. This allows straightforward integration into existing LV panels and MCCs, minimizing retrofit complexity while preserving protection coordination.
The breaker offers 4000 A rated uninterrupted current (Iu) and a 100 kAIC interrupt rating, enabling reliable protection during high-energy faults. This supports robust feeder protection, reduces the risk of collateral damage, and simplifies selecting upstream devices for coordinated protection schemes.
Absolutely. With three poles, a 4000 A Iu, 100 kAIC interrupt rating, and PXR trip unit, the MPSC4N3WEAXX2C is well-suited for motor control centers and high-energy feeders where precise protection and fast fault interruption are essential for uptime and safety.
This model is UL Listed, CE Marked, and CSA Certified, among others. These certifications support global procurement, streamline regulatory approvals, and reduce the risk of non-compliance in multinational installations, helping meet industry standards and customer requirements.
Integration with Power Xpert Protection Manager enables remote monitoring, event logging, and protection management, reducing field service visits and enabling predictive maintenance. This translates to lower downtime, optimized spare parts use, and a favorable total cost of ownership over the life of the installation.
