FAQs

The MPSC304HEAXX2C is a standard-frame, four-pole breaker designed for fixed horizontal mounting, which simplifies retrofit into compatible panels. Zone selective interlocking documents and mounting accessories from Eaton support correct phasing and interlock alignment. Before installation, verify panel rating, busbar spacing, and space for the 14.6 in depth, 16.8 in height, and 21.2 in width. Ensure wiring clearance and torque specifications are followed per the Magnum PXR documentation.
This model is rated for 3000 A with a 100 kA breaking capacity, four-pole configuration, and fixed horizontal mounting. The PXR20 LSIG trip unit provides advanced protection features and selective coordination. Dimensions and mass (14.6 in depth, 16.8 in height, 21.2 in width, 160 lb) influence enclosure design and heat dissipation. These specs together support reliable protection against short circuits and overloads while enabling scalable deployment.
Industries with substantial motor loads and critical feeders, such as data centers, manufacturing plants, and process industries, benefit from the Magnum’s high breaking capacity and coordination capabilities. The four-pole, PXR20 LSIG trip unit supports precise tripping in demanding environments, while the unit’s compatibility with Power Xpert products enables centralized monitoring, reliability improvements, and easier incident analysis for uptime optimization.
The device carries CE Marked, UL Listed, ANSI, CSA, and other certifications, plus KEMA and Lloyd’s Register marks, indicating robust regulatory compliance across major markets. For projects requiring strict approvals or multinational installation, these certifications simplify supplier qualification, reduce validation times, and support traceability and warranty confidence across locations.
Selecting a Magnum with the PXR20 LSIG trip unit and robust certifications reduces downtime risk and expedites maintenance with clear diagnostics and centralized protection management. The unit’s high fault-current handling reduces cascading trips, while compatibility with Eaton tooling and manuals streamlines spare parts and service cycles, yielding lower maintenance costs and higher system availability over the asset life.
