Eaton MPSC404WEAXX2F Magnum - UL Listed 100 kA

High interrupting capacity and four-pole design enable robust protection for high-load circuits. By withstanding 100 kA fault currents and coordinating with downstream protection, the MPSC404WEAXX2F helps prevent cascading failures and minimizes equipment damage. In practice, this translates to shorter outages and improved plant uptime in manufacturing lines and processing plants. Drawout vertical mounting simplifies replacement and maintenance in crowded panels. This installation approach reduces downtime during service calls and lowers risk of wiring errors. When upgrading or retrofitting, the MPSC404WEAXX2F fits alongside existing Magnum or legacy breakers, enabling a smoother transition with minimal panel redesign. PXR20 LSIGAM trip unit provides electronic protection with adjustable settings and fast tripping curves. This enables selective coordination with downstream devices, reduces nuisance trips, and provides clear fault indication for faster diagnostics and maintenance in automation environments. The unit’s substantial frame and robust construction support dependable operation in harsh industrial environments. With 16.3 in depth, 16.8 in height, and 44.1 in width, installation planning and panel coordination become predictable, while the 319 lb mass signals a solid, serviceable device. Certification coverage and cross-compatibility with international standards help future-proof installations. Along with CE, NEMA, and CSA compliance, the unit supports global inventory and service planning. Add-on parts and renewal accessories from the Magnum PXR ecosystem ensure ongoing lifecycle support, reducing downtime and operating costs across expanding facilities.
