High current handling and fault protection: The MPS8404HEAXX2H delivers a 4000 A frame and 85 kA interrupt rating, providing rapid, reliable interruption for dense power circuits. This reduces equipment damage and enables safer operation during short-circuit events, especially in motor control centers and distribution panels where fault currents are high. The four-pole design ensures balanced protection across phases, simplifying wiring and improving reliability in large panel assemblies. Fixed horizontal mounting accelerates installation and minimizes misalignment, which translates to lower commissioning time and fewer field errors. Compact, rugged construction is compatible with standard MCC racks, enabling straightforward retrofits or new builds without custom enclosures. These characteristics support long-term uptime and predictable maintenance cycles.

FAQs

The MPS8404HEAXX2H uses a fixed horizontal mounting suitable for motor control centers and switchgear assemblies. Its four-pole design supports balanced three-phase protection, and the 16.3 in depth, 16.8 in height, and 44.1 in width help determine enclosure fit. Always verify available panel width and mounting rails to ensure proper alignment and secure installation.
Key specs include a 4000 A frame rating and an 85 kA interrupting capacity, four-pole configuration, and a Power Xpert Release PXr20 LSIAM trip unit option. It is UL Listed and CE Marked, with additional certifications, enabling reliable performance in demanding industrial environments and supporting compliance across regions.
Yes, the product supports zone selective interlocking (ZSI) concepts, aided by the PXr release trip unit and Eaton’s protection tooling. ZSI enables faster fault isolation and reduced arc energy. For best results, refer to Eaton’s interlocking papers and ensure proper wiring and coordination with downstream protection devices.
This model carries UL Listed, CE Marked, and CSA Certified labels, along with several other certifications (Lloyd's Register, KEMA, ANSI, DNV GL, ABS). These certifications support global deployment, passing audits, and compliance across industries such as manufacturing, oil & gas, and data centers.
Using Magnum PXR with Power Xpert Protection Manager centralizes protection settings, enabling faster fault diagnosis and reduced downtime. The combination supports predictive maintenance, easier firmware updates, and coordinated protection across devices, which lowers long-term operating costs and extends equipment life while simplifying asset management and reporting.
