Eaton MPS84N4HEAXX2C Magnum low voltage power breaker - UL

Four-pole, fixed horizontal mounting simplifies panel integration and balance of protection across busbars, enabling compact layouts and faster install times. Feature leads to a measurable business impact: streamlined assemblies, reduced commissioning labor, and consistent protection for critical loads in factory lines or data center rooms. Applications include motor control centers and distribution panels where reliable interruption of fault current is essential. The 85 kA breaking capacity provides robust fault handling, reducing collateral damage and maintenance costs during high-energy faults. In practice, this translates to longer equipment life and lower total cost of ownership for heavy-industry environments. The 4000 A current rating supports large feeder protection with minimal nuisance tripping under transient events, improving process stability and operator confidence. Compatibility with PXR20 LSIG trip units enables selective coordination with Power Xpert Protection Manager for centralized monitoring and upgrades. This reduces risk during panel expansions and enables future-proofing of electrical infrastructure. The unit’s weight and dimensions (16.3 in depth, 16.8 in height, 44.1 in width, 319 lb) inform cabinet space planning and lifting requirements, avoiding last-minute installation delays. Certifications including UL Listed, CSA Certified, and CE Marked provide worldwide compliance, while CCC Mark and NEMA compliance support installation in diverse markets. The product supports zone selective interlocking and other safety-enhancing practices described in Eaton’s application notes, helping engineers align with industry best practices and safer-by-design principles.
