Eaton MPS8503VEAXX2H Magnum Breaker - UL Listed, CE Marked

Power Xpert Release (PXR20 LSIAM) trip unit delivers precise, configurable protection for three-pole breakers. This feature improves selectivity across feeders, reduces nuisance trips, and shortens fault clearance times in crowded panels. In motor control centers and distribution boards, the PXR20 enables tailored curves and settings to match load profiles and code requirements. Three-pole, fixed vertical mounting provides a stable, space-efficient footprint for retrofit projects and new installations. This design simplifies alignment with bus sections and supports standard enclosures without custom adapters. The fixed orientation also eases wiring management, speeding field work and reducing setup risk. High fault capability is evident with 85 kA short-circuit rating and 5000 A interrupt rating, ensuring robust protection for demanding environments. Coupled with precise trip characteristics, you get fast isolation of faults, protecting downstream equipment and personnel while maintaining system uptime. Global compliance is demonstrated by CE Marked, UL Listed, ANSI, KEMA, and Lloyd's Register certifications, along with NEMA compliance for rugged conditions. These certifications simplify procurement and regulatory audits across regions, helping you consolidate vendors and reduce risk. Installation and integration are streamlined by compatibility with Eaton Power Xpert Protection Manager and related software. The unit ships with standard inputs and a user manual, and the PXR20 trip unit exposes settings that align with standard protection schemes, easing commissioning and ongoing diagnostics. For retrofit teams, the Magnum's generous footprint and 237 lb weight indicate a solid, heavy-duty clamp-in solution, while the 16.3 in length and 31.1 in width provide ample space for wiring and labeling.
