Feature → Business Impact → Application: Three-pole configuration provides balanced protection across three-phase loads, enabling coordinated shutoff during faults and reducing arc flash exposure in industrial plants. This supports improved safety and uptime while meeting industry standards for three-phase protection in machine centers and panelboards. Feature → Application: Fixed horizontal mounting simplifies retrofits and panel layout planning, enabling straightforward integration into existing switchgear racks without rework. The 4000 A frame and 85 kA short-circuit rating deliver robust fault protection for high-current applications, reducing the risk of cascading failures in manufacturing lines and data centers. Feature → Benefit: No trip unit by default lowers initial cost, while compatibility with Power Xpert Release trip units (PXr) offers a clear upgrade path for selective coordination and advanced protection schemes as your system evolves. Feature → Compatibility: Magnum PXR family and compatible trip units enable future upgrades without replacing the breaker, simplifying maintenance budgets and spare-part planning. Feature → Compliance: UL Listed, CE Marked, and multiple third-party certifications confirm regulatory compliance across global sites, supporting fast design approvals and supplier qualification. Feature → Installation: Fixed horizontal mounting, three-pole configuration, and standard frame sizing streamline installation, testing, and panel commissioning for high-volume projects and OEM assemblies.

FAQs

Yes. The MPS84N3HEAXXSW is a fixed horizontal mounting, three-pole breaker designed for compatibility with Magnum frame assemblies. Its dimensions (16.3 in depth, 16.8 in height, 31.1 in width) and weight (237 lb) help plan space and handling in existing switchgear. For enhanced coordination, pairing with Power Xpert Release trip units in the Magnum PXr family is recommended.
The unit carries UL Listed and CE Marked certifications and supports NEMA Compliant operation. Additional third-party certifications include ANSI, CSA, KEMA, Lloyd's Register, ABS, DNV GL, and SABA listings, providing broad regulatory coverage for global installations and supplier qualification.
Out of the box the model ships with no trip unit, but selective coordination is achievable by installing a Power Xpert Release trip unit (PXr) from the Magnum line. This upgrade path enables precise coordination with upstream protection and improved nuisance tripping performance in complex panels.
Key specs include a 4000 A frame, 85 kA short-circuit rating, three-pole configuration, fixed horizontal mounting, and a weight of 237 lb. The product length/depth is 16.3 in, height 16.8 in, and width 31.1 in. These parameters inform panel cutouts, clearance, and mechanical supports during design and installation.
A comprehensive set of Eaton resources is available, including specification sheets, application papers, UL/Certificates of Compliance, manuals, and protection-manager software. These documents cover selective coordination, renewal parts, and installation guides to support design reviews, commissioning, and ongoing maintenance.
