Drawout vertical mounting with motorized racking streamlines maintenance and swaps during commissioning, reducing downtime and improving operator safety. This configuration enables fast, controlled circuit-breaker extraction and seating, minimizing exposure to live components while meeting plant downtime targets. In practice, technicians gain predictable rack-and-run cycles, which translates to faster changeouts in panel builds and expansions. The three-pole Magnum PXR family delivers 85 kA interrupting capacity with a 5000 A rating, supporting high-energy fault events in demanding facilities. This translates to improved system reliability and lower risk of collateral damage during short-circuits. Site engineers benefit from fewer replacements and extended service intervals when protective devices are matched to load profiles. The unit’s global certifications—UL Listed, CE Marked, NEMA Compliant, along with KEMA, CSA, ANSI, DNV GL, and ABS—facilitate cross-border procurement and installation. Its compact footprint (16.3 in L, 16.8 in H, 31.1 in W) and weight (237 lb) fit large distribution panels with predictable handling. The design supports renewal parts and accessories for Magnum PXR, enabling future upgrades and long-term maintenance planning. Compatibility with Magnum PXR trip units opens a path for field enhancements without replacing the entire assembly, reducing total-cost-of-ownership over the equipment lifecycle.

FAQs

For proper installation, allocate panel space for a 31.1 in width, 16.8 in height, and 16.3 in depth unit weighing 237 lb. Ensure vertical drawout mounting and motorized racking clearances are observed. Verify enclosure compatibility and allow service access around the breaker to facilitate maintenance and future upgrades.
This is a three-pole Magnum device with a 5000 A rating and 85 kA interrupting capacity (ABCABC). Catalog number MPS8503MEAXXSW, no trip unit included by default, designed for drawout installation in double standard frames and compatible with Magnum PXR protection options.
Yes. It carries UL Listed and CE Marked certifications, along with NEMA compliance and additional approvals such as KEMA, CSA, ANSI, DNV GL, and ABS from the provided specification set, supporting installation across global sites with varied regulatory requirements.
The MPS8503MEAXXSW is part of the Magnum PXR family and can be compatible with compatible Power Xpert Release trip units in field upgrades or through labeled product aids. Verify with Eaton’s current renewal parts catalog and project specifications to plan a seamless upgrade path.
Motorized racking enables faster, safer maintenance and reduces downtime during breaker swaps. The robust 85 kA interrupting capacity enhances fault resilience, while multi-certifications simplify cross-site procurement. The ability to upgrade with renewal parts and PX R trip units supports a longer service life and lower total-cost-of-ownership in evolving power architectures.
