FAQs

The MPS8404MEAXXSW is designed as a four-pole, drawout vertical unit with motorized racking mounting, enabling safe and fast maintenance. It fits standard Magnum panel architectures and can be paired with a Magnum PXR protection unit. Ensure panel opening dimensions meet the 16.3 in depth by 16.8 in height footprint and provide proper racking clearance to maximize the motorized system benefits.
Key specs include a four-pole arrangement, 4000 A frame rating, and 85 kA interrupting capacity. The unit ships without a trip unit but is compatible with Power Xpert Release trip units for advanced protection. It employs a drawout vertical design with motorized racking to facilitate safe maintenance and precise coordination within Magnum systems.
Yes, the MPS8404MEAXXSW is suited for heavy industrial switchgear and process plant environments. Its high interrupting capacity handles large fault currents, and its four-pole construction supports complex motor control centers. When paired with a PXR trip unit, it provides scalable protection and coordination across distributed power systems.
This model carries UL Listed, ANSI, Lloyd's Register, CSA, DNV GL, ABS certifications, plus CE Marked and CCC Marked with NEMA compliance. These certifications reduce regulatory risk, facilitate cross-border approvals, and ensure conformity with both industry and regional safety standards for electrical protection equipment.
Maintenance benefits include safer rack-and-replace operations with motorized racking, and the option to upgrade with Power Xpert Release trip units for enhanced protection and coordination. Over time, this can reduce downtime, improve fault diagnostics, and lower lifecycle costs by extending service intervals and simplifying field upgrades in Magnum-based installations.
