FAQs

The MPS8404VEAXXSW is a fixed-frame, four-pole device designed for vertical mounting in LV distribution panels. During installation, verify solid mounting to maintain alignment with bus bars, ensure correct terminal torque per the catalog, and plan for future maintenance access given its substantial weight (approximately 319 lb). The result is secure operation and straightforward retrofits in MCCs and switchgear.
This model comes without an integrated trip unit. For trip-unit functionality, engineers should reference Magnum PXR variants designed for Power Xpert Release, or consult Eaton’s product literature for compatible configurations. This approach preserves protection standards while allowing selective coordination and advanced tripping where required.
The device carries UL Listed, CE Marked, and CSA Certified marks, with additional compliance references to SABA Listed, NEMA Compliant, and CCC Marked labeling. Lloyd's Register and other third-party certifications are listed in Eaton’s documentation, supporting global deployment in regulated environments such as manufacturing plants, data centers, and international facilities.
The MPS8404VEAXXSW is rated for 4000 A with an interrupting capacity of 85 kA. This combination supports demanding feeder protection and motor circuits, enabling reliable interruption of high fault currents while meeting industry protection standards for critical electrical systems.
Typical applications include motor control centers, large distribution panels, process plant switchgear, and industrial power distribution schemes. Its four-pole configuration and robust frame are suited to high-demand environments where uptime, safety, and protection against short-circuits are priorities for engineers and procurement teams.
