High interrupting capacity and robust frame rating provide fast fault clearance, reducing damage to downstream equipment and shortening downtime in critical applications. This translates to lower maintenance costs and improved system availability in motor control centers and switchgear. The three-pole, drawout vertical design with motorized racking enables safer, faster maintenance and easier replacement during routine servicing, minimizing exposure to live components. No trip unit is included by default, offering flexibility to select and install a Magnum PXR release trip unit when a coordinated protection strategy is required, ensuring future-ready protection with minimal retrofits. The extensive certification footprint—UL Listed, CE Marked, CSA Certified, ANSI, KEMA, ABS, DNV GL—provides multi-market compliance and smoother procurement for global projects, while the compact dimensions (16.3 in L, 16.8 in H, 31.1 in W) and 237 lb weight simplify panel layout and shipping. The product is supported by comprehensive Eaton documentation, including specification sheets, application papers, and TCC data for precise coordination with existing protection schemes.

FAQs

This model features a drawout vertical mounting with motorized racking, enabling safer, faster maintenance and straightforward replacement. It is designed for standard 3-pole configurations in switchgear and MCCs, with a compact footprint that fits common panel layouts. When selecting an external trip unit, ensure compatibility with Magnum PXR if a coordinated protection scheme is required.
The MPS85N3MEAXXSW provides high fault-current protection with an 85 kA short-circuit rating and a 5000 A frame context. It carries UL Listed, CE Marked, and CSA Certified marks, along with ANSI, KEMA, ABS, and DNV GL certifications, ensuring broad regulatory compliance for global deployments in both North American and European markets.
Yes, it supports selective coordination when paired with the appropriate trip unit. Eaton offers guidance through application papers such as the selective coordination document IA0120000E3 and the Magnum PXR product aids, which outline coordination strategies and best practices. Note that this model ships without a trip unit by default, so a compatible PXR unit may be added as needed.
The breaker measures 16.3 inches in depth, 16.8 inches in height, and 31.1 inches in width, with a shipping weight of approximately 237 pounds. This data aids in accurate panel space planning, wiring clearances, and safe handling during installation and maintenance in industrial facilities.
A full suite of technical resources is available, including the Eaton Specification Sheet for MPS85N3MEAXXSW, user manuals for Magnum PXR, application and coordination papers, time/current curves, and certificates of compliance. These documents support correct installation, configuration, maintenance planning, and ongoing compliance across jurisdictions.
